Abstract
A mechanical shock sensor including a diaphragm suspended about its edge to an elevated pedestal and a pattern of piezoelectric material attached to the diaphragm surface. A proof mass is attached beneath the diaphragm surface and centered along a vertical axis passing through the diaphragm and the concentric piezoelectric materials. Electrical conductors are attached to the first and second concentric electrically conductive layers on piezoelectric material and are connected to a circuit capable of responding to the piezoelectric signals developed thereby.
