Organic Sensor Array Distributed in Flexible and Curved Surfaces

Abstract

Organic sensor array is fabricated on a curved plastic film substrate of which Gauss curvature is finite. Herein, a soft robot finger is proposed as one of the test cases of curved surface device that has artificial tactile sense by detecting slight deformation induced by touching an object. The curved surface sensor array is made by thermal molding of planer device array on thin plastic film. Observed electrical current in each sensor pixel reflects strain distribution and time response induced by external slight displacement applied.
