ABSTRACT:
A flexure in a transducer such as an inertial guidance accelerometer for suspending a force sensitive element to a mounting base includes a reduced thickness central portion and a pair of relatively thick ribs disposed on opposite sides of the central portion. An electrically conductive coating is disposed on at least one face of the central portion to provide electrical connections to components located on the element. The reduced thickness of the central portion minimizes errors caused by stresses in the interface between the conductive coating and the element and the relatively thick ribs provide a desired strength and spring rate for the element suspension.
