Human skin completely covers body parts with diverse shapes, can cure physical injury spontaneously, and sensitively detects a touch. Researchers have investigated e-skin devices, concentrating on the sensing functionality of the skin. Still, most e-skin devices have restrictions in their shapes and in realizing multiple functionality in one device. Here, application-oriented 3-dimensional hydrogel device which can heal mechanical damage spontaneously and detect accurate touch point are demonstrated as a new artificial skin devices. The 3-dimensional ring and fingertip- shaped artificial skin devices are successfully prepared to fit completely on finger models. Upon a human finger contact, the devices provide the accurate positional information of an arbitrary touch point even on a complex-shaped 3-dimensional artificial skin device without complicated device preparation or data processing.
