Flexible visuo-haptic display

Abstract

We have developed an flexible electro-active polymer (EAP) actuator and a thin flexible visual display with 3×3 array configuration via polymer technology. The flexible actuator consists of nine EAP cells vertically moving in response to change in their thickness. The flexible display uses polymer based optical waveguide allowing light to scatter only at specific area. A pressure sensor is installed under the integrated module. The performance of the actuator is proved to be sufficient for satisfying perceivable range of human touch sense.
