Researchers from Sungkyunkwan University in Korea and the University of Nevada have developed a flexible tactile display that can wrap around the fingertip, palm, or arm.

The key material in the display is an electroactive polymer that can stimulate the skin. It consists of eight layers of dielectric elastomer actuator films sprayed with electrodes in a specific pattern.

The soft display might provide a means of communication for the visually impaired, as a tactile display cloth, virtual reality keyboard, tele-surgical glove, and for other uses.
