British materials firm Peratech is developing artificial electronic skin for robots at MIT's Media Lab that will allow machines to know where they have been touched and with what degree of pressure. So you could tickle, back-slap, or caress your favorite robot, and it would know the difference.
Peratech is using its "quantum tunnelling composite" (QTC) material to createfor intelligent machines at MIT. QTC is a low-cost, flexible, and electrically conductive material that would give robots a new means of interacting with people.
Made of spiky metallic nanoparticles and silicone rubber, QTC works by changing from an insulator into a conductor when pressure is applied. Peratech says robots equipped with QTC skin would be able to detect where they have been touched using a matrix of sensors on various body parts.
Peratech's material has been used as a touching technology in NASA's Shadow Robot Company. No doubt robotic hands and manipulators would benefit from touch-sensitive skin for better grasping of objects, but I bet developers will take a lot of interest in this sort of material, too., and well as by the
