The EasyTouch capacitive touch sensor can be used with either the Arduino platform or the Raspberry Pi mini PC using the EasyPlug breakout board if required.

The sensor forms an image and OpenCV detects the actual touch configuration. It appears you can use the raw data from the Arduino, too, but it might be a little harder.

The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.

Touchstone Semiconductor's Martin Tomasz explains how to interfact to capacitive touch sensors using basic 555-timer circuits.

In projected capacitive touchscreens—the touch technology used in every new smart phone—noise bombards the touch sensor whenever it’s in use.

In a world increasingly dominated by touchscreens, a London design studio is taking an approach to touch that's both low(er)-tech and innovative at the same time. Bare Conductive raised over US ...

The discrete prototype demonstration functions to transmit the touch sensor data over the DisplayPort AUX channel while driving the digital and analog needs of the LCD panel.

A finger-heating effect has been observed on mutual capacitive touch sensors with plastic film overlay. The symptom is exhibited as serious sensitivity degradation when there is a greater than 10°C ...
