Digital burst mode, charge-transfer (QT™) sensor capable of detecting near-proximity or touch. It will remain on as long as a touch is detected. This is useful for applications such as hearing aids, which must remain on as long as the hearing aid is worn. The sensor projects a touch or proximity field to several centimeters through any dielectric including glass, plastic, stone, ceramic, and even most kinds of wood. It can turn small metal-bearing objects into intrinsic sensors, making them responsive to proximity or touch. It is designed specifically for human interfaces and includes all hardware and signal processing functions necessary to provide stable sensing under a wide variety of changing conditions. Only a single low-cost capacitor is required for operation.
