ABSTRACT:
A piezoelectric acceleration transducer characterized by a flexible element formed of a piezoelectric material with two external electrodes, a support member having two plate-type supporting components between which the flexible member is arranged, and a carrier plate to which the support member is mechanically and electrically connected such that the principal axis of sensitivity of the flexible element lies in the same plane as the carrier plate. The supporting components may be formed of a nonconducting material with a electrically conductive coating on the side facing the flexible element and at a point of contact with the carrier base. Alternatively, the supporting components may be made from an electrically conductive material.
