PublishTime： 2023-11-12 Article Source：Nanochap News

With the accelerated pace of modern life, people's demand for quality sleep is gradually increasing. As a wearable smart device, the smart eye mask provides a convenient way to promote sleep and is able to detect EEG brain waves, heart rate, blood oxygen saturation, anxiety, relaxation, etc., helping people to understand their own sleep conditions for timely adjustment. Nanochap Vital Signs Parameter Detection Chip EPC001 can also be used in the smart eye mask and has certain technical advantages.

First of all, Nanochap by the "national key research and development program" led by a team of chief scientists, independent research and development of brain wave concentration, and relaxation algorithms, with a rapid response, high accuracy, and strong anti-interference and other outstanding advantages. Through in-depth research and analysis of brainwave signals, the algorithm is able to quickly detect the user's concentration and relaxation, and make timely adjustments accordingly. When the user wears the smart eye mask for learning or relaxation, it can accurately recognize the changes in the user's brain waves, thus providing a comfortable experience that better fits the user's needs.

Secondly, the integration of the Nine Senses EPC001 vital signs parameter detection chip in the smart eye mask further enhances its performance and functionality. The chip integrates a high-precision EEG/ECG/EMG/PPG analog front-end and a powerful RISC-V microcontroller (MCU). By monitoring the user's brain waves, ECG signals, and pulse waveforms, the Smart Eye Mask is able to gain a comprehensive understanding of the user's physiological state and adjust environmental factors accordingly to provide a more personalized and effective service.

The smart eye mask plays an important role in promoting sleep. It is designed to relieve eye pressure, block out light, and reduce eye fatigue, improving the user's sleep quality. Combined with the self-developed algorithm of Nanochap's Nine Senses EPC001, the smart eye mask not only monitors the user's brainwave changes but also makes corresponding adjustments according to the user's sleep state. For example, when Nine Senses EPC001 detects that the user is in deep sleep, the smart eye mask can automatically adjust environmental factors such as temperature and light to create a more comfortable atmosphere for sleep. This personalized service helps to improve sleep quality and enables users to achieve a healthier and more fulfilling sleep state.
