Abstract :
This paper presents the first-of-its-kind wireless and power-free micro pressure sensor for gastrointestinal (GI) monitoring by leveraging the LC tank based mutual inductance detection mechanism. Compared to previous reported pressure sensors, this device is featured with simple device structure, miniaturized device size (e.g., no batteries and electrical components for energy transfer) and comparable performance (sensitivity of 0.0261 kHz/kPa (-50~50 kPa)).
