ABSTRACT:
A beam-type sensor capable of measuring displacement or acceleration includes a thin, flexible sheet of piezoresponsive material defining broad sides and a proximal end. In order to optimize boundary conditions, the proximal end of the sheet is supported by a clamp that provides a “clean” transition between support and no-support. Electrical connections to conductors associated with the broad sides are integrated into the clamp. In one embodiment, two sheets of piezoelectric material are connected electrically in parallel. In another embodiment, two sheets of piezoelectric material are connected electrically in series.
