Chest and Abdomen Respiratory Monitoring by Large Area Piezoresistive Array

Respiration is an essential human function. Common breath detectors include airflow testing and belt-wearing testing. However these techniques will bring discomfort to patients with back pressure sores or back burns caused by long-term bed rest. In order to solve the above problem, we designed a a large area piezoresistive array, which is made of graphite and silver paste. The force distribution and dynamic waveform of the resistance array are used to analyze the breathing rate and determine the prone position, so it helps the medical diagnosis and treatment in the hospital.This device is of great significance to improve patients' diagnosis and treatment experience.
