Patent number: 11737366Abstract: A sensor apparatus includes a first of a plurality of layers having a top layer, a bottom layer, and at least one intermediate layer having an electrical conductor layer, each of the top layer, the bottom layer, and the at least one intermediate layer is disposed in direct contact with a respective adjacent layer. A second of the plurality of layers is disposed in direct contact with the first plurality of layers such that the bottom layer of the second plurality of layers is disposed in direct contact with the top layer of the first plurality of layers. The first and second plurality of layers are productive of a piezoelectric voltage absent of an external current producing device and in response to being deformed, and are productive of a change in capacitance in response to being deformed.Type: GrantFiled: February 23, 2018Date of Patent: August 22, 2023Assignee: ROGERS CORPORATIONInventors: Karl E. Sprentall, Trevor Polidore, Robert Mone, Michael Lunt, William Kwan
