Northwestern University researchers have developed a new thin, wireless system that adds a sense of touch to any virtual reality (VR) experience. Not only does this platform potentially add new dimensions to our long-distance relationships and entertainment, the technology also provides prosthetics with sensory feedback and imparts telemedicine with a human touch.

Referred to as an "epidermal VR" system, the device communicates touch through a fast, programmable array of miniature vibrating actuators embedded into a thin, soft, flexible material. The 15-centimeter-by-15-centimeter sheet-like prototypes comfortably laminate onto the curved surfaces of the skin without bulky batteries and cumbersome wires.
