Abstract
A method for manufacturing high deformation piezoelectric actuators and sensors using a continuous tape manufacturing process is provided. The ceramic layer is dispensed between two metal/adhesive layers to form a composite tape and is tack welded together. Lengths of composite tape are heated and then cut into individual actuators. A special pattern punched in the tapes allows for ease of alignment of the layers of the actuators.
