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 ...

3M Touch Systems announces the commercial availability of a new polyester-based projected capacitive touch screen solution. MicroTouch Flex Capacitive Touch Sensors from 3M are ideal for high-volume ...

Capacitive sensing libraries for the Arduino and just about every other microcontroller platform have been around for ages now, but if you’d like to put a slightly complex cap sense pad in a PCB ...

This PLL-based circuit implements a touch-switch circuit using the PC board or small metal pads as sensors; it is radiometric and thus insensitive to changes in temperature and supply voltage.

This application note discusses the advantages, techniques, limitations, and general recommendations of Metal Over Capacitive technology in sensors. The layout of this app note includes the general ...

Capacitive touch sensors have made homes i n scores of MP3 players and mobile phones. Of course, the mobile arena is no longer the only bastion for these devices. Today, sensor technology has ...
