Abstract

In one embodiment, a self-powered tactile pressure sensor includes a flexible substrate, an array of piezoelectric crystalline nanorods each having a bottom end and a top end, the nanorods being generally perpendicular to the substrate, a top electrode that is electrically coupled to the top ends of the nanorods, and a bottom electrode that is electrically coupled to the bottom ends of the nanorods.
