PIEZOELECTRIC POLYMER SENSOR DEVICE

摘要

A sensor device includes at least one piezoelectric polymer film supported on a plate that is positioned relative to a machine such that a force used during a manufacturing process involving the machine is incident on the plate. The piezoelectric polymer film provides an electrical output indicative of the incident force. In a disclosed example, a single piezoelectric polymer film extends across a substantial portion of a surface area of the plate. In another disclosed example, a plurality of piezoelectric polymer film sensor elements area are arranged symmetrically about a location where the incident force is expected to be most prominent.
