It will project a sense field through almost any dielectric, like glass, plastic, stone, ceramic, and wood. It can also turn small metal-bearing objects into intrinsic sensors, making them respond to proximity or touch. This capability coupled with an ability to self calibrate continuously can lead to entirely new product concepts. The device is designed specifically for human interfaces, like control panels, appliances, toys, lighting controls, or anywhere a mechanical switch or button may be found; it may also be used f……
