Abstract :
The arterial pulse monitoring is significant in assessment of cardiovascular system. To improve the performance of arterial pulse sensor, a new non-invasive arterial pulse detecting system composed of a nc-Si:H/c-Si heterojunction MOSFET pressure sensor fabricated by micro-electromechanical systems (MEMS) technology and detecting circuits has been developed. The arterial pulse detecting system can simultaneously detect, display, store and analyze pulse signals. The sensitivity of the arterial pulse sensor is 0.45 mV/kPa.
