The QT110 / QT110H charge-transfer (“QT’”) touch sensor is a self-contained digital IC capable of detecting near-proximity or touch. It
will project a sense field through almost any dielectric, like glass, plastic, stone, ceramic, and most kinds of wood. It can also turn
small metal-bearing objects into intrinsic sensors, making them respond to proximity or touch. This capability coupled with its ability to
self calibrate continuously 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; it may also be used for some material sensing and control applications provided that the presence
duration of objects does not exceed the recalibration timeout interval.
The IC requires only a common inexpensive capacitor in order to function. A bare piezo beeper can be connected to create a ‘tactile’
feedback clicking sound; the beeper itself then doubles as the required external capacitor, and it can also become the sensing
electrode. An LED can also be added to provide visual sensing indication. With a second inexpensive capacitor the device can
operated in 2-wire mode, where both power and signal traverse the same wire pair to a host. This mode allows the sensor to be wired
to a controller with only a twisted pair over long distances.
Power consumption is under 20
μ
A in most applications, allowing operation from Lithium cells for many years. In most cases the power
supply need only be minimally regulated.
The IC’s RISC core employs signal processing techniques pioneered by Quantum; these are specifically designed to make the device
survive real-world challenges, such as ‘stuck sensor’ conditions and signal drift. Even sensitivity is digitally determined and remains
constant in the face of large variations in sample capacitor C
S
and electrode C
X
. No external switches, opamps, or other analog
components aside from C
S
are usually required.
The device includes several user-selectable built in features. One, toggle mode, permits on/off touch control, for example for light
switch replacement. Another makes the sensor output a pulse instead of a DC level, which allows the device to 'talk' over the power
rail, permitting a simple 2-wire interface. The Quantum-pioneered HeartBeat signal is also included, allowing a host controller to
monitor the health of the QT110 continuously if desired. By using the charge transfer principle, the IC delivers a level of performance
clearly superior to older technologies in a highly cost-effective package.
