SAFETY RELATED

Similar to the principle of electrocardiograph or sphygmomanometer used in the physical examination, CURVEX uses the metallic copper sensor safe to human body to detect the bio-electricity signals on the epidermis of human body. The brainwave signals of human body are centered in the head, while the area that is the most beneficial to brainwave detection is located in the forehead without coverage of hair. Therefore, CURVEX uses a single-point metal sensor to collect the bio-electricity signals.

CURVEX will process these signals to some extent, e.g. clutter filtration, noise reduction and analytical calculation, and then send the analyzed brainwave state to iPad or other intelligent terminals via Bluetooth.

Ear clip plays a role of “sensing circuit”. There are two sensors in the ear clip, one of which is reference electrode, and the other of which is grounded, the same as the clip at the ankle while electrocardiography. Cardio-electricity is the strongest bio-electricity signal in human body, so it can be accurately collected in a circuit crossing half of the body, while cerebro-electricity is much weaker, so it can be collected in a circuit crossing half of the head. The ear clip of CURVEX is precisely ergonomically designed, comfortable to wear, without causing any discomfort to the earlobe.

CURVEX uses the internationally popularized Bluetooth 3.0 wireless transmission standard protocol, and many Bluetooth headsets have also used the same wireless technology. However, the data size and power transmitted by CURVEX are much less than the audio and voice of general Bluetooth headsets. Therefore, compared to the commercially available Bluetooth headsets, CURVEX has nearly zero radiation.

CURVEX has passed the certification of Bluetooth SIG, FCC, CE, SRRC and other radio safety certification authorities, and has been authorized by MFi (Made for iPhone). The built-in lithium battery has also passed the UL1642 safety certification. The materials used by CURVEX are environmentally-friendly, recyclable, free from harmful ingredient, consistent with the international environmental protection ROHS certification.

No. CURVEX can detect the changes in the strength and frequency of brainwaves in the left forehead of the brain only. These changes can reflect different human brain states only, e.g. focused, relaxed, fatigued, nervous and anxious, and will not reveal the concrete thinking information. Therefore, CURVEX will not reveal the user’s thinking.

CURVEX trains the brain’s self-state-regulating ability, a spontaneous regulating skill. Many Apps will offer some tips to control the brain states (e.g. auto-suggestion, imagination method, breathing regulation and Alpha acoustic wave resonance, etc.) You can pace yourself or develop new skills according to these tips. CURVEX can help you to validate whether the brain is really in the focused or relaxed state and give the visual and acoustic feedbacks and tips by means of multimedia. Through these feedbacks and practices, you can gradually develop the self-regulating skills best fit for yourself, and then gradually consolidate these abilities through long-term training, thus flexibly used in the daily life and learning.

Everyone has different trigger points to enter the focused or relaxed state. However, CURVEX can help you to find your exclusive focused or relaxed “note” more scientifically and more rapidly.

CURVEX uses the application of cerebro-electricity feedback technology in the multimedia field. Many research institutions and universities at home and abroad have carried out scientific experiments on how this technology improves the human psychological health, and have proved that this technology can bring the improvement to different extents. The cerebro-electricity feedback technology has always been widely used in the treatment of children hyperactivity, the most popularized method without side effect in addition to the drug therapy. In our opinion, this technology not only can be utilized in the treatment of children with hyperactivity, but also should be popularized to the public consumers to help more people to improve the brain self-control ability.


Many apps of CURVEX has the effect evaluation functions, e.g. the calendar in the “Mind Yoga” or the parent interface in the “Mind Ant”. You can record your brainwave data for a long time with these functions to observe the change trends, and the effects will be clear at a glance. Meanwhile, the system will provide evaluations and suggestions based on the user performances. The parent interface also provides a ranking of cloud brainwave database, so that you can understand the ranking of your child in the focus among the nationwide children of the same age. You can rapidly understand the brain self-control performance levels of yourself and your child.

CURVEX trains a kind of spontaneous “proactive focus”, different from the “passive focus” stimulated and induced by the outside world. Many educational experts think that the proactive focus is more important! In many CURVEX games, the user should proactively enter the focused state to pass the challenges and obtain the rewards. Difficulties will be gradually increased with the games, so the user should be more proactively focused and more rapidly for a longer time, thus the user’s spontaneous focus will be gradually improved.

Any long-time use of tablet PC or mobile phone will cause adverse effect on the eyes. Therefore, we suggest that each continuous use time of CURVEX not exceed 30min. You can set the play time and the rest time on the parent interface of the games. Additionally, in part of relaxation game apps, the user will often close the eyes to relax, which will greatly reduce the eye pressure, and the long-time relaxation and meditation will be helpful for the brain health. Therefore, if you are worried about your child’s vision or brain fatigue, you can encourage your child more to interact with the relaxation games (e.g. the relaxation mode in the “Mind Yoga” or “Think-tank Star Crisis”).

HOW TO WEAR

Please ensure that CURVEX has sufficient electric quantity and has been turned on, and that the red/blue Bluetooth indicators are flickering alternatively. Then, enable the Bluetooth function in the Bluetooth setting of the terminal device, and then wait several seconds. “CURVEX” should appear in the Bluetooth list, and auto-pairing will start next. Some old devices might request you to enter the Bluetooth pairing code. Please enter “0000”. If successful pairing, the device in the list has been connected, and only the blue Bluetooth indicator of CURVEX is flickering.

Please refer to the “CURVEX Quick Start Guide” inside the packing box, or download the app “CURVEX” from App Store, where the animation video will teach you how to conduct the Bluetooth pairing.

  • Please restart the terminal device and clean the caches in the Bluetooth list. Excessive Bluetooth or previously connected CURVEX will result that the device cannot search the new Bluetooth again. Restart the device and conduct the pairing again.
  • Please check the Bluetooth indicators on the CURVEX. If only the blue indicator is flickering, it indicates that CURVEX has connected with another device. Please turn off the Bluetooth of another device to disconnect, and then conduct the Bluetooth pairing with the new device.
  • If you use the mobile phone or tablet PC with Android system, please refer to the manual and ensure that your device is provided with the Bluetooth function and supports the connection with the third-party Bluetooth. Some Android devices use the closed Bluetooth protocol, and it will result that CURVEX cannot set up the Bluetooth connection with such devices.
  • If you use the Apple’s iOS device (iPhone or iPad), please ensure that the device system has been updated to the latest version. See the following link for the compatibility:
http://CURVEX.dk/

• Please read and familiarize the descriptions of connecting signals in the “Signal Description” in the app “CURVEX” (search the keyword “CURVEX” on the App Store, and you can download for free), and operate according to the descriptions and suggestions.
• Please click the connecting signal icon on the top right corner to open the advanced detection function. Observe the raw brainwave pattern, and operate according to the app descriptions.
• Please try to close the apps running in the background, particularly the apps compatible with CURVEX or using Bluetooth. These apps are possibly occupying the Bluetooth channel.
• Please restart the device and connect the Bluetooth again.

Actually, to wear the CURVEX correctly, just ensure that the two metal sensors contact the forehead and earlobe. Please refer to the “CURVEX Quick Start Guide” inside the packing box, or download the app “CURVEX” from App Store, where the animation video will teach you how to wear the CURVEX correctly. After wearing the CURVEX correctly, you should be able to hear two prompt tones.

After wearing the CURVEX correctly, you should be able to hear two prompt tones.

Because the cerebro-electricity signal is extremely weak, the brainwave detection stability is easily interfered by the outside world. Here are some frequently-seen circumstances affecting the stability:

1. Shake violently or blink or talk frequently, resulting in myo-electricity interference.

2. Hair, earrings or other objects contact with the metal sensor, or cover up the contact with the metal sensor.

3. Excessive sweat or cosmetics blocks the metal sensor. Try to wipe the sweat or other impurities on the forehead and sensor.

4. The metal sensor does not fully contact with the skin. It is suggested to adjust the ear clip to ensure that the two sensors inside the ear clip are close to the earlobe, and additionally, observe whether the metal sensor on the forehead is close to the skin contact surface on the forehead. Adjust the elastic band properly to allow the forehead to be close to the sensor.

5. There are strong electromagnetic wave interferences or lots of electronic devices (particularly wireless devices) in the surrounding environment, e.g. mobile phone communication, TV screen, air-conditioning and camera, etc..

6. The environment is too noisy, and high-decibel acoustic wave will also produce interference.The above circumstances can be troubleshot in the advanced detection functions (refer to the app “CURVEX” -> signal descriptions -> advanced detection functions).To achieve the optimal experience effect, please exclude the above circumstances to ensure the cerebro-electricity detection stability. Alternatively, you can try to wear the CURVEX again and wait several seconds patient until the prompt tones and the green icon of correct wearing appear.

CURVEX uses the lithium battery (160mAH) that has passed the UL1642 safety certification. A full battery can be used for 4-6 consecutive hours. The USB charging source is 5V, 500-1000mAH (standard USB power source). You can use the computer USB port or the iPhone/iPad charger.

Q&A

A1: Our company is a high-tech company engaging in the brainwave interaction & emotional guidance teaching cloud platform and the individual & family brainwave entertainment & interaction solutions. Our R & D team has introduced the advanced foreign brainwave technology and present in the animation form, so that the users can enjoy the games when use, and can receive the focus and relaxation training. Children might be addicted to the ordinary games once playing, but our training software is to enable the children to learn to relax and focus. What we communicate to them is a kind of method. Therefore, our product is inherently different from the game.

A 2: Most of all, our app is different from the traditional game in the playing method. We use the most advanced “brain-computer interface” technology to detect the extremely weak cerebro-electricity signals on the head epidermis, and judge the different behaviors and states based on his frequency, thus realizing the playing method of game controlling by mind, and our game design is very lively.

A 1: Our apps are mainly used to train the focus and relaxation in the game-playing manner. What we advocate is the value proposition of “healthy brainwave and new family”. Game & animation is one of our manifestation modes. We have developed different multimedia mind interaction experience, relaxation guidance and other apps specific to different ages, e.g. Meditation Garden, for the purpose of enabling the users to make their brainwaves more healthy in a simple, convenient and educational manner.

A 1: Simply speaking, our product can enable the users’ brain to learn to relax and focus. At present, our company has the programs developed for the children aged 4-14. Nowadays, the children have heavy learning stress and learning burden. How to relax themselves in the heavy learning? How to focus under the heavy stress? I think these are the topics concerned by the students and parents. Based on the statistical analysis of data from our previous pilot projects, after trained by our training software system, many children’s focus have indeed strengthened. Additionally, we believe that in addition to the children, other remaining family members can also use our product to make some mindful parent-child interactions, because a healthy brainwave is beneficial and vital to everyone and his relatives and friends.

A2: Simply speaking, our product can enable the users’ brain to learn to relax and focus. CURVEX translates the human brainwaves into the visible data map with the advanced technology to help the users to understand their focus and relaxation, thus improving their poor self-control.

A3: If old people use our product to do some brainwave control training for a certain time daily, it would be helpful for them. For example, it would be helpful to relieve the Alzheimer’s disease.

A: Simply speaking, our product is to help the students to improve their self-focus and relaxation. Actually, these abilities exactly can urge them to develop good living and learning habits, e.g. listening carefully in class, sleeping on time, restricting the time to watch animation and finishing the homework on time; if a child can do these like an adult, will you still be worried about his poor academic results? For the children with psychological problems, we suggest them to receive the treatment from professional psychologist. If our product is used as adjuvant therapy, the result will certainly be better.

A: Our induced brainwave chip is imported from foreign country. At present, China still has no ability to produce this chip. As you know, the vehicle of the same brand imported from foreign country will be much more expensive than the domestic one. To buy a high-tech product, we not only see its existing presentational value, but more importantly, we own the high-tech value contained behind the product. It can enable our brain to learn to relax and focus freely, which will be faster and more significant than the effect of more cram schools.

A2: CURVEX is a product in combination with software and hardware, the true value of which is reflected in its abundant software apps. Apps are constantly updated. In other words, the value of CURVEX is also constantly improved. In addition, the product has passed the Apple’s MFi official certification, with the quality guaranteed. Because it is a product officially certified by Apple Inc., the price of general MFi product will be 20%-30% higher than that of other products.

A3: The value of CURVEX is that it helps you (or your child) to understand the brain state, and to train the brain focus and to help release the emotional stress through the educational interesting apps, so as to reach a healthy brain state. This is closely related to our daily life, learning, work and social contact.

A: Human brain is like a machine running at a high speed. Failure at any part will possibly result in brain discomfort. Brainwave is a microscopic biological wave truly existing in the brain, which can be quantified by data. The scientist researches over the years show that the brainwave value can feed back the brain health condition. Our R & D personnel have utilized the scientist research result over the years to conclude that when human brainwave is at a certain range value, it is the most healthy brainwave. The healthy brainwave we advocate is that people should understand their own brain at a deeper level microscopically, thus knowing the brain health condition. People are afraid of the unknown world. Only the own health can be controlled by themselves and clear data and image can be seen, can they be at ease. We have morphologized the brainwave, and the morphologization data should be known by people. Therefore, brainwave product can become a necessity of life.

A2: As a useful metaphor, we can regard the four brainwaves of the brain as the four gears of automobile. Delta is first gear, theta is the second gear, alpha is the third gear, while beta is the fourth gear. No gear can fit for all the driving states, and no brainwave state can fit for all the life challenges. If a certain gear of automobile cannot be used, or we forgot to use it, there will be something wrong with the automobile. If we start with the first gear, and then shift to the fourth gear directly (the second and third gears omitted), the automobile fuel consumption will be increased sharply, and the repair charge will be high. So is the brain. But unfortunately, too many people have omitted the second and third gears (theta and alpha brainwaves) when use of the brain, so that the brain working efficiency is decreased and the medical charge is increased. How does this happen? Let’s give an example to describe the modern life. When deep sleep (delta brainwave state) in the early morning, you are awaken up by the alarm clock suddenly. There is not enough time, and you must take immediate action (beta brainwave state). A nervous, anxious and hurried day starts!!! You drink a cup of coffee to keep awake (beta brainwave state), because the caffeine can inhibit the theta and alpha brainwaves and enhance the beta brainwave. You work in the nervous, stressed or anxious state all day long (beta, beta and beta brainwave state) until fatigued in the evening, and you throw yourself into the bed and fall asleep (directly entering into the delta brainwave state). You do not have time to relax and to feel fatigued during the day (no time to enter into the alpha and theta brainwave states). In the modern life, too many people drive the brain like this, suddenly and powerfully from the first gear to the fourth gear, and directly from the fourth gear to the first gear.

Q&Q&A and terms

CURVEX is an intelligent device which can detect the brainwaves. It can detect the brainwave signals in the frontal lobe (the brain forepart is responsible for immediate memory and outside perception) via the forehead sensor to contact with the skin. By analyzing the frequency of these signals, CURVEX can know the brain states, e.g. focused, relaxed, anxious and nervous, etc.. Users can execute the instructions on the intelligent terminal to interact with apps by regulating their own psychological states to change the brainwave frequency, so as to realize the “Mind Control”. 

Brainwave (EEG), like the cardio-electricity (ECG) and myo-electricity (EMG), is a bio-electricity, produced by human organ. Brainwave is bio-electric current produced by connection and interaction between neurons.

Human discovered the brainwave (EEG) in 1920, and discovered the changes in the brainwave rhythms in the human states. Later, the brain science circle set these rules into a set of standards, forming the EEG today. Generally speaking, people are in the alpha and beta states when awake, and in the theta or delta state when sleep.

Alpha (8-13 Hz) is a relaxed state when people are consciously awake, e.g. walking in a park, doing yoga or closing their eyes meditatively. It is widely believed that this state can promote the physical health condition, particularly the sub-health condition of urban high-stress population. Alpha state can reduce the physical stress hormone secretion, and improve the insomnia, low immunity, obesity, hypertension and other sub-health conditions.

Beta brainwave is generally divided into low beta wave (13-17Hz, also called SMR wave) and high beta wave (18-30Hz). Low beta wave is the brainwave when people are in the working state, a focused state, where the limb movement is under control. High beta wave is the brainwave when the brain is in the stressed, nervous and excited state. If the brain is in this state, a lot of energy will be consumed, and the brain will feel fatigued, anxious and stressed. Beta brainwave is particularly important for people’s working and learning performance. Therefore, cultivation and induction of beta brainwave in the childhood will be greatly helpful for the future growth of the children. If child cannot produce beta wave, there is probably a lack of certain nutrient elements during the brain development, resulting in attention-deficit hyperactivity disorder (ADHD).

Theta wave (Hz 3-7) is a brainwave between waking and sleeping. When our left brain is in the theta wave state, the left brain will be “closed”, and the right brain will be “activated” to become active, clouding in consciousness, but the creative inspiration is endless. Theta is a state the artists and writers often pursue for, and people can reach this state under the effect of drugs. Of course, we can also reach this state naturally when we are meditating and deeply relaxed.

Delta (1-3Hz) is a state of deep sleep, which allows the body and brain to take full rest and get revitalized. Delta wave will also be produced when neonate brain is not fully developed

The product is comprised of the core module and the sensor support. Core module is comprised of operational chip, controlling circuit board, battery, Bluetooth connecting chip, Apple’s decoding chip (used to connect the iOS device), buzzer and lamp control indicator, etc.. Sensor support is comprised of 3 dry-electrode (wet-electrode without conductive adhesive applied) metal sensors, i.e. EEG, REF and GND. Generally speaking, EEG electrode should keep a certain distance from REF electrode to ensure the potential difference and the loop integrity. GND electrode should be placed at a stable contact point.

The core electronic components used by CURVEX are from Silicon Valley, NeuroSky, iSSC and Apple Inc., which are combined to become the most miniaturized brainwave sensing product up to now through the precise design. The product has obtained many patents and proprietary intellectual property rights, including the PCT international patent. The software is independently researched and developed by CURVEX.

CURVEX has been striving to develop the third-party developer ecological chain system. Welcome the developers to join in the brainwave civilian use. The API interface of CURVEX is open-source and free. Developer is required to pay attention to the official account CURVEX only, leaving the E-mail by contact with the customer service. We will send the API and example document to you. Upon completion of development, we will also help you to shelf the app and popularize your product, and 100% of the revenue from the app will be completely dominated by the developer. Meanwhile, CURVEX can also conclude a cooperation agreement on hardware sales with the developer, binding the developer’s app for joint sales revenue splits.

Compared to the second generation, the first generation can export the clear raw brainwave, which is generally used in scientific research, rather than ordinary users.

CURVEX MARKETING TERMS AND FAQ

The methods of regulating the focus and relaxation vary with each individual, but some universal methods can be tried by you. Whether focused or relaxed, you should keep the gentle and calm emotion without impulsive or negative emotion and thought, which is the key to regulate the brainwave rapidly. In addition, focus and relaxation are not opposite to each other, but can reach a high level simultaneously. Therefore, some methods can be used to improve the focus and relaxation simultaneously.

Focus: Focus on thinking one thing, perhaps work plan or life scenario, with the attention towards the future, rather than the memory of the previous unhappiness to the greatest extent; let go the thought, and then focus on something at the moment, and observe the details; adjust the breathing, and give yourself positive psychological suggestion; close your eyes to discover any particular sound or smell you have never noticed.Relaxation: Adjust your body posture to make it feel comfortable; soothe the breathing and feel the breathing rhythms; hum a favorable song with lively rhythms.

Our product uses the same battery and Bluetooth module as those for majority of commercially available Bluetooth headsets, and has passed the CE mandatory certification, which is safe.

Our training is based on the “cerebra-electricity neural feedback” technology, which is a mature technology researched since 1960s, mainly used in foreign laboratories and hospitals previously. Lots of papers and successful cases can be searched on the network. It is a recognized focus training method. Of course, like any other training, you should persist for a period of time to achieve the desired results. Parents should also encourage the children more during the training to enhance the children’s confidence.

Please check whether your CURVEX is worn correctly when use. The correct wearing method is as follows: leave the metal chip of forehead hair band at the frontal bone 1-2cm above the eyebrow, and keep all the collected metal points fitting to the skin. Meanwhile, please keep the skin in contact with the metal chip clean and dry when use. Do not contact with the hair or other metallic substances in order not to affect the signal reception. When wearing, do not tighten the hair band too much. Just wear according to the above method. Most people do not know how to focus the attention in the use process. They often believe that once they exert their strength, they are focused. At this moment, the user might have his brows knitted unnaturally, resulting that the chip for collecting brainwaves cannot fit to the skin well. So sometimes the signal is well received, but sometimes the signal is interrupted. If the brainwaves still cannot be collected when you adjust the wearing position repeatedly and hand over the device to other people to wear, you should consider that the device might have malfunctioned, and you should return it to us for after-sale service. We provide the 6-month free warranty. The device will be handled and returned to the customer in no more than 24h after the device is returned to us.

Our product analyzes the current brain state directly by the brainwave signal, and the result is most scientific and accurate and can stand the test. It is normal for the mismatching between the data and the feeling, because your feeling is from your own external information processing and feedback, which cannot truly reflect the brain state. This is also the reason why meditation involving the personal perception requires training, but cannot be mastered easily by everyone.

CURVEX, a high-tech enterprise founded in 2020, has been specializing in transformation of scientific research achievements in the cerebro-electricity field of neuroscience to civilian use. So far, it has produced two consumer products and 2 supporting apps in addition to the abundant hardware accessories. It is a well-known enterprise in the field. It has established good cooperative relationship with DTU, DIF and other domestic brain science and neuroscience cutting-edge academic institutions.

The first generation and the second generation have the same basic functions. Compared to the second generation, the first generation can export the clear raw brainwave, which is generally used in scientific research, rather than ordinary users.

Step 1: Download and install the app.

Step 2: Enable the mobile phone Bluetooth function, and start the head ring module to search the pairing. If paired, it is OK.

Step 3: Wear the head ring on the head. If two beeps are heard, it is OK.

Step 4: Open the app installed in the mobile phone to use.

  1. The flagship version can be used in scientific research, while the Light version cannot.
  2. The flagship version has the intelligent EmoLight display function. When you wear for training, if you are highly focused, the red light will be on; if you are highly relaxed, the blue light will be on. The Lite version does not have such function.
  3. The Light version is more suitable for the customers with larger head circumference.

The flagship version and the Light version have the same basic functions. Compared to the Light version, the flagship version can export the clear raw brainwave, which is generally used in scientific research, rather than ordinary users.

Different versions have the same data accuracy, but have different brainwave signal clearness when brainwave output. With respect to the scientific research version, our company provides a data interface for the scientific researchers who intend to carry out the secondary development, so as to facilitate the researchers to acquire the brainwave data conveniently; with respect to the public version, just as its name implies, we do not provide the clear brainwave data for the users who do not carry out the secondary development, and all the data analysis and processing will be completed by our app for the customers. This is the difference between the two versions. The brainwave authenticity, operability and other experiences are just the same. No trouble will be caused to your use. You can use our product with ease.

A lot of billionaire CEOs including Steve Paul Jobs are loyal fans of meditation movement. In their opinion, meditation can improve the memory, attention and EQ, thus obtaining better career development and life quality. Medically, there has been no final conclusion about the practical effect of meditation, but more and more people think this is at least an effective relaxation form.

After you wear this product, it can detect your real-time brain state, and then regulate your brain state by training with the software in the mobile phone based on this state, mainly the focus and relaxation.

This can become the psychological research, particularly the EEG data, which has the reference value for the learning, working and relaxation data collection.

Short battery endurance: 1. The battery is not fully charged, and the battery voltage reaches the cut-off voltage only, resulting that the battery charging capacity fails to be full, thus affecting the endurance; 2. To protect the power supply system, we deliberately heighten the cut-off voltage for the low voltage of battery, sacrificing the nominal endurance time, in order to protect the longer battery life. Generally, after beeps, you can still start again, and if you want to continue to play, the battery can still provide the endurance capacity for about half an hour. The official 4h refers that the battery reaches the saturation state when physical charging, and runs under high load all the time until the battery capacity is fully consumed, which is a user mode test.

  1. Firstly, exclude that the tinnitus is interfered by mechanical or intermittent sound source; 2. Exclude that your body static value is higher (generally, the higher static value might reach several thousand or several ten thousand volts). When collection, the voltage will enter the host, resulting in internal circuital current fluctuation, and noise current will occur at the buzzer, thus producing the sound. Our product has the anti-static function, but also has certain voltage value protection range. Therefore, in this case, you are suggested to turn off the host, and the product will balance the static electricity automatically. Then restart and use again.

50% are for psychological training, 30% are for development and scientific research, 15% are individual customers, and the remaining 5% are for unknown purpose.

When the brainwave is releasing, it can be transmitted to any part of the body via bone conduction. But with the long-distance transmission, the brainwave signal will become weaker and weaker, and it will be mixed up with many cluttered bio-electricity waves. The collection points constitute a loop via the conductor. After the passageway is detected, you can start to collect the bio-electricity waves uninterruptedly. If the waves collected from the part far away from the head are mixed up with many cluttered bio-electricity waves, after the filtration of related chips, some brainwave ingredients will still be translated into digital signals and transmitted to app for decoding. At this moment, there will be change in the value of energy strip, but you will feel that the controllability is extremely poor when use. The device now cannot identify the body parts intelligently. If yes, the price will certainly be much higher.

The device is worn on the head for collection, where there are lots of biological brainwaves are releasing. In this way, more than 90% of the device bio-electricity collected is brainwave. After data processing and decoding, the data will be authentic, and the device will be strongly controllable. Like the advertisement putting, which is also advertising campaign, the reason why the prime time is selected to achieve different putting effect is that the user intensiveness is different.

Please check whether your headset is worn correctly when use. The correct wearing method is as follows: leave the metal chip of forehead hair band at the frontal bone 1-2cm above the eyebrow, and keep all the collected metal points fitting to the skin. Meanwhile, please keep the skin in contact with the metal chip clean and dry when use. Do not contact with the hair or other metallic substances in order not to affect the signal reception.
