Abstract

Embodiments of tactile stimulation apparatuses and components of such apparatuses are generally described herein. For example, in one embodiment, a tactile stimulation apparatus is provided. This tactile stimulation apparatus has a composite section comprising an insulation region and a semiconducting region that is proximate to the insulation region. This insulation region is touchable by a body member. Additionally included is a voltage source proximate to the semiconducting region. Here, the voltage source is configured to charge the semiconducting region to an electric potential, which produces an electrosensory sensation on the body member.
