Capacitive touch sensors are entirely in the domain of DIY, requiring little more than a carefully-chosen conductive surface and a microcontroller. This led [John Phillips] to ask why not embed such ...

Researchers have developed a flexible optical touch sensor that can simultaneously detect the strength and location of pressure with high sensitivity and stability. The advance in tactile sensing ...

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 ...

Capacitive sensors work by detecting the change of capacitance introduced by the finger touching near the electrode. Such change is so small that detecting it unambiguously is challenging, and has ...

The touch sensors on smartphones and tablet computers allow people to sling angry birds across the screen or scroll through pages of cat pictures with a gentle finger swipe. To detect a user’s touch, ...

You can’t have a touch sensitive switch without a way to detect the presence of a finger! A touch sensor, especially a capacitive touch sensor, has some surprisingly sophisticated electronics to ...
