ABSTRACT:
A piezoelectric energy source having a piezoelectric transducer mounted in a housing and a movable piston arranged in the housing to bias the transducer to provide a desired electrical output. The piston exerts pressure on the transducer in response to a pyrotechnic charge and is locked in a predetermined biasing position by a locking arrangement such that a constantly effective pressure is exerted on the transducer.
