Abstract
Official abstract text for this publication.
A touch panel is provided. The touch panel includes an electroactive polymer (EAP) actuator which is deformable when protruded or depressed locally at a part to which a driving voltage is applied; and a flexible touch sensor which is disposed on the EAP actuator. The flexible touch sensor is deformable locally in correspondence with a deformation of the EAP actuator, and senses an input according to a contact or pressing operation.
First claim
Opening claim text (preview).
What is claimed is: 1.
