A CAPACITIVE TRANSDUCER WITH CUTTING AREAS

摘要

The invention provides an actuator made from a layer of an elastomeric material (126) with an actuation area (129) in which a top surface and an opposite back surface are both covered by an electrically conductive material (128). To enable cutting of the actuator into smaller actuators, the elastomeric material comprises a cutting area (130) in which at least one of the top and back surfaces is not covered by electrically conductive material. In one embodiment, the elastomeric material is rolled to form a tubular body (124). The invention further provides a method of making a plurality of actuators by cutting an actuator into smaller pieces.
