EEG detectors play an increasingly important role in modern daily life, they help people understand their brain state more deeply through scientific and technical means, so as to make more informed decisions and choices in daily life.

By capturing and analyzing brainwave signal data, EEG testers are able to reveal key information about an individual's sleep quality, emotional stress, brain habits, and more. This is certainly an important tool for those who may be suffering from anxiety, depression, or other psychological distress.

Nanochap Nine Senses Series EPC001 chip is a sensing chip system designed for bioelectric signals. It integrates high-precision ECG, EEG, EMG, PPG analog front-end and a powerful RISC-V microcontroller, which not only possesses a high degree of sensitivity and accuracy, but is also capable of completing complex data processing in a short period of time. The outstanding performance of this chip system gives it a wide range of application prospects in the field of health monitoring.

Nanochap Nine Senses Series EPC001 chip in the EEG detector:

• The weak electrical signals generated by neuronal activity in the brain are captured by the electrodes of the EEG detector;

• Nine Senses Series EPC001 chip captured these electrical signals, after the chip internal amplification, filtering out high-frequency noise and low-frequency interference, improve the signal-to-noise ratio of the signal;

• The amplified and filtered EEG signals are then processed by the data algorithm inside the chip to extract useful information;

• On the basis of data algorithm processing, the EEG detector will further extract specific indicators, such as wave amplitude, frequency, phase, etc., in order to gain a deeper understanding of the state of the brain.

The Nine Senses Series EPC001 chip is implanted into the EEG detector to detect the human body's EEG signals in real time and convert them into readable digital data. The Nine Senses Series EPC001 also features a variety of other sensor processing units and contains a wealth of health testing algorithms (cuff-less blood pressure, cardiovascular function index, anxiety index, fatigue index, blood oxygenation, brainwave concentration, relaxation, etc.) that are widely used in a wide range of multi-parameter, high-performance portable health testing products.

Its versatile peripheral interfaces allow the SoC to be extended externally with multiple different sensors. The powerful RISC-V core MCU processing and its memory space allows for the integration of different wireless transceiver stacks (e.g. BLE or NFC) for the transmission of measurement data.

The application of the Nine Senses Series EPC001 chip also makes it easy to process and share data with the EEG detector. Traditionally, EEG detectors need to transmit data via a wired connection to a medical device for analysis. The EEG tester with Nine Senses Series EPC001 chip can transmit real-time EEG data to smartphones or the cloud via Bluetooth or wireless network connection, realizing online data processing.
