Electrick combines conductive coatings or additives with electrodes and algorithms developed at Carnegie Mellon University. It can create a touchpad on just about any surface—walls, steering wheels, toys—to control lights and other devices.
Electrick’s spray primes a surface to better conduct electricity, and low-voltage electrodes placed around the perimeter of the area can register changes in the current caused by touching the surface in a particular spot.
