The electronic board implements the following functionality.

Obtaining an electroencephalogram (EEG). The signal is recorded by digitizing the signal by an ADC module with a frequency of 250 Hz, from leads that are dry Pogo Pin electrodes (25 pin: O1 (106), T3 (107), T4 (109), O2 (110)) in the form of a comb of pins spring-loaded gold-plated contacts, as well as common and reference electrodes (GND (113), REF (108)), located on the frontal part and representing dry flat electrodes in the form of gold-plated conductors.

Obtaining a photoplethysmogram by digitizing the PPG module (112) of the reflected signal in the red or infrared ranges from the PPG sensor (114), located in the right temporal region.

Obtaining data from microelectromechanical systems by digitizing data from the gyroscope and accelerometer by the MEMS module to analyze acceleration and angular velocity along three orthogonal axes.

Transferring collected and packaged data via the BLE 5.0 standard communication module to a personal computer (PC) and/or telephone.

This technical solution is implemented as follows.

After pressing the device's power button and closing the contacts, the battery supplies a reference voltage to the electronic board and its modules. All modules are initialized. After that, the microprogram is read from the ROM module, according to which the device subsequently functions.

In the “default” mode, the device is ready to operate and switch modes (impedance measurement, EEG signal measurement, PPG, MEMS sensor indicators). The LED blinks uniformly at a frequency of 1 time per second.

To put the device into pairing mode with the target device (for example, a PC and/or phone and/or tablet), you should hold down the power button for 2 seconds, and the LED will blink at a frequency of 2 times per second. This will start the firmware “pairing” mode and activate the corresponding mode of the Bluetooth module.

After pairing via Bluetooth with the target device, its Bluetooth MAC address data will be transferred by the Bluetooth module to the ROM chip and saved (up to 10 devices). Thus, the pairing procedure will not be necessary again the next time you turn it on.

Turning on and off again occurs by pressing the power button for 1 second.

In impedance measurement mode, the ROM, ADC, RTC (quartz crystal), Bluetooth modules are activated, and the potential difference between the target electrodes (T3, T4, O1, O2) and the reference (REF) electrode is measured to determine the quality of the electrode-skin contact. The measurement results are transmitted via the Bluetooth module via a communication channel to the target device in kOhm units.

In the EEG signal measurement mode, the ROM, ADC, RTC (quartz resonator), Bluetooth modules are activated and the potential difference between the target and reference electrodes is measured. The ADC polls the target electrodes with a frequency of 250 Hz, then this data is sent to the Bluetooth module for sending to the target device.

In the PPG signal measurement mode, the ROM, ADC, RTC (quartz resonator), Bluetooth modules are activated and measurements of reflected light in the red or infrared ranges coming from the PPG sensor with a frequency of 100 Hz are carried out, then this data is sent to the Bluetooth module for sending to the target device . PPG (photoplethysmography) is a method of measuring blood volume in vessels using light radiation. PPG works on the principle of determining tissue density.

The PPG sensor is connected to the PPG module and the general electronic board of the device, and is designed to: receive information, send data to the electronic board, and then send it to the target device.

The PPG sensor includes internal LEDs that can operate in both the red and infrared ranges, a photodetector and low-noise electronics with an external light suppression function.

The device uses a type of sensor that measures reflected light.

In the signal measurement mode from the MEMS sensor, the ROM, ADC, RTC (quartz resonator), Bluetooth modules are activated and position measurements are made along three orthogonal axes, then this data is sent to the Bluetooth module for sending to the target device.

The operation of the device allows operation in the mode of simultaneous measurement of EEG, PPG, MEMS data; in this case, according to the firmware mode, ROM, ADC, RTC (quartz resonator), Bluetooth, PPG, MEMS modules are activated. In this case, all allocated space in the Bluetooth data package will be occupied.

Switching modes is done by sending commands to the device via the Bluetooth protocol.

In measurement mode, the LED lights up evenly.

If the device is turned on and is in “standby” mode (no measurement mode is selected), then following the firmware mode, the device will turn off after 15 minutes to save battery power.

The neurointerface with a built-in neuroamplifier is implemented on the basis of a Texas Instruments ADS 1294 ADC with a sampling frequency of 250 Hz, with leads T3, T4, O1, O2 (according to the international 10/20 scheme), a PPG signal analysis module, with a sensor located in the right temporal region, MEMS module to analyze acceleration and angular velocity along three orthogonal axes. The device includes a BLE 5.0 standard communication module.

The electronic module and the battery are two parts placed on a flexible printed circuit board.

To record EEG signals, the device uses dry electrodes (25 pin: O1, T3, T4, O2) in the form of a comb of spring-loaded gold-plated contacts (Pogo Pin). The general and reference electrodes (GND, REF) are located on the frontal part and are dry flat electrodes in the form of gold-plated conductors of a flexible printed circuit board of the device. The electrodes are located according to an expanded electrode arrangement, according to the 10-20 system: O1, T3, T4, O2. The designation of channel names is strictly regulated by the International Federation of Clinical Neurophysiology.

To register PPG signals, the device uses an integrated PPG system that combines the functions of Heart Rate and a pulse oximeter through the use of an LED and a photodetector operating in two modes: infrared and red spectra.

To control the movement of the device in space, an integrated MEMS system is used, combining a gyroscope that determines angular velocities along three orthogonal axes and an accelerometer that determines acceleration along three orthogonal axes.

The device has one on/off button, one connector for connecting to a charger, two LEDs - green and red. When the device is turned off, it is completely de-energized and consumes no energy. The device is self-powered in the form of a built-in Li-Pol battery. To connect the device to the charger, a cable with a magnetic connector on one side and a USB connector on the other side is used.

The device supports the following operating modes:

resistance measurement - to determine the quality of fit of the electrodes;

sending charge values of the built-in battery;

data measurement (EEG signal, PPG signal and MEMS, or combined EEG and PPG signals);

charge and complete charging of the device.

After launching the user application and authorization (if user registration is necessary), the software, upon request, searches for a device ready to connect via Bluetooth. If such a device has been found, the quality of electrode application begins - resistance measurement; if the quality is satisfactory and the resistance readings for each electrode are less than 1000 kOhm, it becomes possible to switch to the EEG and PPG recording mode.

In the mode of recording physiological data, for EEG, the device conducts surveys with a frequency of 250 Hz, for each of the electrodes, with a set of 8 samples, they are packaged in a BLE package and sent via a Bluetooth communication channel to the target device running the software.

For PPG data, the device conducts surveys with a frequency of 100 Hz, and sends the data in the same BLE packet via Bluetooth as the EEG data.

Additional technical advantages of this technical solution.

Thanks to the design of PogoPin electrodes for collecting EEG signals, high-quality data collection is achieved from areas of the head covered with hair, without any preliminary preparation (using saline solution and/or gel).

Thanks to the placement of electrodes for EEG recording at positions T3/T4/O1/O2 and the reference “on the forehead”, high-quality signal acquisition is achieved from all areas of the brain located in the cerebral cortex, in particular: reliable detection of Alpha, Beta, Theta rhythms brain.

The use of PPG and MEMS sensors in conjunction with EEG sensors at the above locations makes it possible to enrich physiological data and use hypotheses associated not only with EEG, but also with movement and heart rate data, building algorithmic solutions at the “junction of scientific fields.”

The use of a stretchable tape in the design of the device allows you to adapt its size to almost all head sizes.

All elements of the device are interconnected and placed inside a flexible silicone case made of medical silicone ToolDecor T 125 (or silicone ToolDecor T 20-240). The length of the flexible tape is chosen to provide maximum coverage of head sizes. In the back of the device's silicone body there are fasteners for a flexible stretchable elastic band that is adjustable in length, which presses the device to the person's head.

The device is intended for individual use.

In these application materials, a preferred disclosure of the implementation of the claimed technical solution was presented, which should not be used as limiting other, private embodiments of its implementation, which do not go beyond the scope of the requested scope of legal protection and are obvious to specialists in the relevant field of technology.
