Pressure influences on the vibration characteristics of piezoelectric circular microdiaphragm based pressure sensors are investigated theoretically and experimentally. It was demonstrated that only Bessel function of zero order, m = 0, participates in the vibration modes of the microdiaphragm symmet
## a b s t r a c t In this work piezoelectric composite charge based sensors are developed, aimed at quasi-static pressure sensor or switch type applications. The use of piezoelectric composite materials allows for manufacturing robust devices which can easily be integrated with conventional polym
