A Smart Oxygen Supply Control System Based On MEMS Capacitive Pressure Sensors

A new smart oxygen control system (SOCS) that regulates the oxygen supply to patients is presented in this paper. The system is designed for patient smart oxygen delivery in hospitals. The operation is based on MEMS Pressure Sensors and its scope is to minimize the losses of oxygen during in-hospital use as well as monitoring the oxygen consumption. Dedicated CMOS electronics are used to perform sensor signal conditioning and calibration. It is autonomous using Li-Po battery and it is wireless connected with mobile devices and an IoT platform Experimental results are also provided.
