Abstract
A piezoelectric transducer is disclosed for providing haptic feedback. The transducer has a stacked structure including a protective layer, a piezoelectric layer, two electrodes positioned on the top and bottom of the piezoelectric layer, an adhesive layer positioned over the piezoelectric layer, and a substrate layer positioned on top of the adhesive layer. The transducer is cured using an autoclave process giving it a curved shape which facilitates electrical connection with a printed circuit board. Curved and custom-shaped molds may be used to effectively increase and precisely control the curvature of the transducer. The transducer may be used to provide haptic feedback in trackpads, keyboards, touch displays, and virtual buttons. One implementation is a bimorph piezoelectric transducer that includes two piezoelectric layers.
