Initial Progress Toward a Surface Morphable Tactile Interface

We demonstrate an initial progress prototype toward a surface morphable tactile interface. The surface is composed of thin film type electro-active material (EAP) and its initial shape is maintained to be a flat membrane. Surface of the membrane is designed to be protrusive by electric field. The height of the protrusion and transition speed of the shape change would be controllable by amplitude and frequency of driving signals.
