1. Product Introduction

The sleep monitoring belt is equipped with ultra-thin, highly sensitive thin-film sensors, pressure sensors and piezoelectric thin-film sensors. The ultra-sensitive thin-film pressure sensors measure tiny vibrations generated by heartbeats and breathing. Built-in algorithms are integrated into the MCU of the acquisition circuit. The device transmits vital signs including heart rate, respiratory rate and body movement to mobile terminals and central management platforms on PC via 4G/NB-IoT IoT network, and sends alert notifications when readings exceed preset thresholds.
