  • Surface-mount piezoceramic accelerometer and method for making
    Patent number: 5235237
    Abstract: A piezoceramic accelerometer of the cantilever bending-beam bimorph type is provided with housing structure of straightforward easily-manufactured design. Because of its design features, the accelerometer is comparatively low in cost, rugged, reliable, and inherently low in internal capacitance. Consequently, a self-generated signal of favorable value proportionate to applied acceleration is provided by the accelerometer. The accelerometer provides for use of Surface Mount Technology (SMT), which allows further manufacturing cost reductions in uses of the accelerometer.
