The SPE-002 thin film piezoelectric sensor is a highly sensitive sleep monitoring sensor. When the sensor senses dynamic signals such as heart rate, breathing, and pulse during human sleep, micro-strain is generated inside the sensor, and an electrical signal is generated between the upper and lower electrode surfaces of the piezoelectric film. The signal is amplified and filtered by the electrical circuit, and then processed by data program to obtain the desired vital signs information.
