Here we introduce a high-resolution tactile display based on the integration of 4,320 actuators with a density of about 300 actuators per cm2 into an array displaying both visual and tactile information. The actuators are fabricated simultaneously by UV-patterning. Intrinsically active polymers called "smart hydrogels" are used as actuators which are sensitive to changes in temperature. The high resolution temperature field is controlled by a computer using an optical interface that is controlled by a computer. Thus the temperature is adjusted for each actuator and it can be independently controlled. An actuator pixel changes color from transparent to opaque providing a visual monochrome functionality. The altitude and the elasticity change as well. Therefore the tactile display is able to generate artificial impressions about contours, textures, profiles and the softness of a surface. The actuators are covered by a thin foil …
