IC
The QT100 charge-transfer (‘QT’) touch sensor is a self-contained digital IC capable
of detecting near-proximity or touch. It will project a touch or proximity field through
any dielectric like glass, plastic, stone, ceramic, and even most kinds of wood. It can
also turn small metal-bearing objects into intrinsic sensors, making them responsive
to proximity or touch. This capability, coupled with its ability to self-calibrate, can lead
to entirely new product concepts.
It is designed specifically for human interfaces, like control panels, appliances, toys,
lighting controls, or anywhere a mechanical switch or button may be found.
