Abstract

Precisely stamped flexible pressure sensors are being developed to realize artificial skin or biomedical applications like prosthetic skin. In order to fabricate flexible ultra-sensitive artificial skin, a large array of tangible pixel pressure sensor with highly ordered sharp tips are necessary. We demonstrate here flexible, highly sensitive capacitive pressure sensor stamped with biocompatible polyurethane (PU) rubber from inexpensively self-assembled honeycomb-shaped polystyrene (PS)-based block copolymer master pattern.
