Mechanical-electrical transducer

Abstract

The invention relates to a mechanical-electrical transducer having a bridge circuit formed on an insulation layer through an electrical interconnection of expansion-sensitive thick-film resistors by means of conductor tracks. The insulation layer is arranged directly on a metallic component that is to be mechanically loaded, and being intimately connected to said component by means of a thermal process. In this case, in the event of mechanical stressing of the component, an electrical signal corresponding to the expansion of the thick-film resistors can be tapped off. In order that the mechanical-electrical transducer exhibits a small electrical offset in the output signal in the event of mechanical loading, the metallic component to be loaded comprises a thermally post-hardening metal or a thermally post-hardening metal alloy.
