Abstract
The subject invention provides composite articles (20, 120) and associated systems (32, 132). A first composite article (20) includes a piezoelectric layer (22) having a piezoelectric property. The piezoelectric layer (22) is sandwiched between a first conductive layer (28) and a second conductive layer (30). At least one of the conductive layers (28, 30) is a conductive polymer having an electrically conductive property. A second composite article (120) includes first and second piezoelectric layers (122, 124) having a piezoelectric property. The first and second piezoelectric layers sandwich an insulating layer (126). A first system (32) and a second system (132) each include a control device (34) electrically connected to the first composite article (20) or the second composite article (120), respectively. The control device (34) measures an electrical signal generated by the respective piezoelectric layers (22, 122, 124) and/orproduces an electrical signal to actuate the respective piezoelectric layers (22, 122, 124).
