1. A device comprising:
- a touch screen including semiconductor material and insulator material that insulates the semiconductor material against galvanic contact by a body member of a user, the semiconductor material being chargeable to an electric potential that produces an electrosensory sensation on the body member of the user; and
a voltage source galvanically insulated from the semiconductor material and configured to generate an electric field that charges the semiconductor material to the electric potential via a capacitive coupling of the voltage source to the semiconductor material.

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.

14. A method comprising:
-
detecting that a body member is performing a touch on a touch screen that includes semiconductor material and insulator material that insulates the semiconductor material against galvanic contact by the body member, the semiconductor material being chargeable to an electric potential that produces an electrosensory sensation on the body member; and causing a voltage source galvanically insulated from the semiconductor material to generate an electric field that charges the semiconductor material to the electric potential via a capacitive coupling of the voltage source to the semiconductor material.
