ABSTRACT:
A flexure in a force transducer, as an inertial guidance accelerometer, for securing a force sensitive element to a mounting base includes one or more flexure sections having one or more recessed surfaces which are substantially coincident with the neutral bending plane of the flexure. Electrically conductive coating on the recessed surfaces provide electrical connections to components located on the force sensitive element. The conductive coatings on or near the neutral bending plane of the flexure sections minimizes bending moments caused by stresses set up between the conductive coatings and the flexure which may in turn lead to bias errors. At the same time, the flexure configuration provides for the desired strength and spring rate for the force sensitive element.
