This device allows each electrode to project an independent sense field through glass or plastic. These devices require only a few inexpensive passive components per sensing channel. The devices are designed specifically for human interfaces, such as control panels, appliances, gaming devices, lighting controls, or anywhere a mechanical switch may be found. Each key channel operates independently, and can be tuned to a unique sensitivity level by simply changing setup values in an EEP...
