Abstract
A piezoelectronic device with novel force amplification includes a first electrode; a piezoelectric layer disposed on the first electrode; a second electrode disposed on the piezoelectric layer; an insulator disposed on the second electrode; a piezoresistive layer disposed on the insulator; a third electrode disposed on the insulator; a fourth electrode disposed on the insulator; a semi-rigid housing surrounding the layers and the electrodes; wherein the semi-rigid housing is in contact with the first, third, and fourth electrodes and the piezoresistive layer; wherein the semi-rigid housing includes a void. The third and fourth electrodes are on the same plane and separated from each other in the transverse direction by a distance.
