Claim 0:
1. An apparatus configured to stimulate sensate skin, the apparatus comprising:
a multilayer sheet comprising a polymer layer adapted to mechanically deform upon application of a voltage to the polymer,
the multilayer sheet secured to a substrate,
the polymer being piezoelectric polyvinylidene fluoride;
a first and a second electrode disposed upon the polymer layer, and
a source of electrical stimulation coupled to drive the first and second electrode with an alternating current signal to vibrate the polymer layer;
wherein the first and second electrodes are disposed on a first side of the polymer layer, the first and second electrodes being interdigitated;
the multilayer sheet having a first edge attached to the substrate and a second edge free of the substrate, the second edge free of the substrate being adapted to stimulate the sensate skin.
