Phys .org: New tech puts virtual sense of touch at our fingertips

Phys .org: New tech puts virtual sense of touch at our fingertips. “The system, developed by researchers at Northwestern University and described in the journal Nature, incorporates 32 individually programmable actuators—a device that emits electric impulses or vibrations—which are embedded into a pliable material made from silicone that adheres to the skin. Controlled by a wireless touchscreen such as a smartphone or tablet, each actuator—the size of a small coin—vibrates to create the perception of touch. The user can control the pressure and the pattern of the sensation.”
