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 ...

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 ...

Texas Instruments just released a product they call the Capacitive Touch Boosterpack which is basically a touch-sensitive shield for the Launchpad. The video after the break shows an unboxing and ...

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.

San Jose, Ca. – Atmel Corporation has just released to volume production its new maXTouch family of capacitive touchscreen controllers, capable of supporting an unlimited number of unique simultaneous ...

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 ...

Electric guitars are great, but they’re just so 20th century. You’d think decades of musicians riffing on the instrument would mean there are no hacks left in the humble axe. You’d think so, but you’d ...
