Touch sensors have been around for years, but recent advances in mixed signal programmable devices are making capacitance-based touch sensors a practical and value-added alternative to mechanical ...

Capacitive touch switches work by measuring the change in capacitance of a PCB (printed-circuit-board) pattern depending on the placement of a user’s finger over a sensing pad. Capacitive switches are ...

Electromechanical switches are simple, cheap, and widely available (Fig. 1). However, they’re also plagued with a number of disadvantages, including wear with repeated use, and the potential for ...

Adafruit has announced the availability of a new 2.8 inch TFT display offering a resolution of 240 x 320 pixels and a capacitive touchscreen interface that can be used for a variety of different ...

The excitement sparked by Apple iPhone's touch screen has created much hype about projected capacitive touch technology. However, in terms of market share or applications, projected capacitive touch ...
