Abstract:
Piezoelectric actuator apparatus and methods for providing tactile feedback are described herein. An example piezoelectric actuator assembly includes a support plate having a recessed well and conductive contact disposed within the recessed well of the support plate. A piezoelectric element has a first layer composed of an electrically conductive material and a second layer adjacent the first layer composed of a piezoelectric material. The piezoelectric element is disposed within the recessed well so that the first layer directly engages the conductive contact and the second layer is to be electrically coupled to a ground via a flexible conductive lead.
