They project sense fields through almost any dielectric, like glass, plastic, stone, ceramic, and wood. They 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 leads to entirely new product concepts. These devices are designed specifically for human interfaces, like control panels, appliances, toys, lighting controls, or anywher...
