Abstract

The piezoelectric air pump is a thin, compact, real silent, non-vibration, and lightweight. In this study, we developed the bloodpressure (BP) monitoring system, based on the finger volume-oscillometric method, using the piezoelectric air pump. Firstly,Pumping characteristics were experimentally investigated. Secondly, the simultaneous BP measurement was performed for onehealthy male (age: 22 years old) using the electronic sphygmomanometer and the prototype system. A load pressure over 200mmHg for BP measurement were achieved with an applied voltage of 15 Vpp and a driving frequency of 23.8 kHz ~ 24.2 kHz.The 4.989 mmHg/s pressurizing speed was controllable by the pulse frequency and delay time. Mean blood pressure and systolicblood pressure were achievable in the finger photoplethysmogram with the cuff. Future work will focus on improvement of thecontrol method for the linear load pressure increasing and the calibration pressure sensor for the high accuracy BP measurement.In conclusion, these findings suggest that it is possible to measure BP with real silent and non-vibration using a piezoelectric airpump in the finger.
