In today's pursuit of precision medicine and intelligent health, Nanochap Electronic Technology Co., Ltd. has given a new life to the traditional medical device, EEG cap, with its innovative EPC001 Vital Signs Parameter Detection Chip.

Core technology advantages of EPC001 chip

The EPC001 chip is a sensing chip system designed for bioelectrical signals, integrating high-precision electrocardiogram (ECG), electroencephalogram (EEG), electromyogram (EMG), and pulse wave (PPG) analog front-end, and built-in a powerful RISC-V microcontroller. This design enables the EPC001 chip to be used in EEG caps with the following significant technical advantages:

1. All-round physiological monitoring: EPC001 chip surpasses the traditional EEG cap, integrating EEG, ECG, EMG and pulse wave and other signals detection, providing all-round health data.

2. Instant data analysis: Built-in RISC-V processor accelerates complex data analysis, EPC001 provides rapid feedback on physiological conditions, which is extremely valuable for medical monitoring.

3. Long-lasting and Low Power Consumption: Optimized low power consumption design supports the stable operation of the EEG cap for a long period of time, reduces the need for charging and improves the user experience.

4. Compact and portable design: EPC001 chip is highly integrated, making the EEG cap lightweight and easy to carry, ensuring convenient and comfortable use.

Brief description of the operation principle

The operation principle of EPC001 chip in EEG cap mainly includes three key steps: signal acquisition, signal pre-processing, data processing and transmission:

1. Signal Acquisition: The electrodes on the EEG cap closely fit the scalp and capture the weak electrical signals generated by the neurons in the brain. These signals enter the system through the input interface of the EPC001 chip. 2. Signal pre-processing: The signals are captured in the EEG cap.

2. Signal pre-processing: The raw signals are first amplified and filtered by the analog front-end of the EPC001 chip to improve the signal-to-noise ratio and usability of the signals.

3. Data Processing and Transmission: The pre-processed signals are fed into the RISC-V microcontroller for further processing and analysis. Users can view and analyze these data through the accompanying software or applications to understand their physiological health status.

Comparison with Traditional EEG Cap

Compared with the traditional EEG cap, the application of EPC001 chip in EEG cap brings the following significant advantages:

1. Accurate Diagnosis Improvement: EPC001 chip brings comprehensive and accurate health data to EEG cap by virtue of high-precision multi-parameter detection, helping doctors and researchers to accurately assess user's health.

2. Efficient Data Processing: The built-in RISC-V microcontroller allows the EPC001 to instantly process large amounts of data, ensuring real-time feedback from medical monitoring and enhancing diagnostic efficiency.

3. Optimized user experience: Low power consumption, long-lasting battery life and highly integrated design make the EPC001-driven EEG cap lightweight, comfortable and easy to use, which greatly enhances user satisfaction.

4. Widen the field of application: EPC001's multi-parameter detection features expand the scope of application of EEG caps, not only limited to neuroscience and clinical, but also covers exercise, emotion, sleep monitoring and other daily health management, benefiting the public's life.

The application of Nanochap EPC001 vital signs detection chip in EEG cap not only reflects its excellent core technology advantages, but also brings new development opportunities in the field of medical technology.
