ABSTRACT:
A thin, piezoelectric membrane provided on both surfaces with electrodes, which may be disc-shaped or ring-shaped, is made to oscillate in the piezoelectric manner and the membrane is arranged to have some exterior force or pressure applied thereto, whereby changes in the frequency of oscillation are in response to the size of the force exerted on the membrane.
