Title: (EN) ACCELERATION MEASURING DEVICE AND METHOD FOR THE PRODUCTION OF AN ACCELERATION MEASURING DEVICE OF SAID TYPE
Abstract:
(EN)

An acceleration measuring device includes a piezoelectric system, a seismic mass, and a base plate. The seismic mass exerts onto the piezoelectric system, a force that is proportional to the acceleration. The piezoelectric system responds to the force by generating piezoelectric charges that are electrically transmitted as acceleration signals. The seismic mass includes a first mass element responsible for generating positive piezoelectric charges. The seismic mass includes a second mass element responsible for generating negative piezoelectric charges.
