Claim 4:
5. A method of providing haptic stimulation to sensate skin comprising:
coupling an alternating current signal generator to drive a first and second electrode of a multilayer sheet, the first and second electrode disposed upon a polymer layer comprising polyvinylidene fluoride, the polymer layer, first electrode and second electrode comprising a multilayer sheet; and
vibrating the polymer layer by enabling the alternating current signal generator; and
coupling vibrations of the polymer layer to the sensate skin;
wherein the first and second electrodes are disposed on a same first side of the polymer layer, the first and second electrodes being interdigitated, the multilayer sheet being configured with a first edge attached to a substrate and a second edge being free of the substrate and configured to stimulate the sensate skin.
