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 ...

I am trying to test a capacitive touch sensor. Specifically, I want to show that it registers a specific change in capacitance. Capacitance is defined as: C = A * Eo * Er / d Keeping A, Eo and d ...

Capacitive displacement sensor’s touch-free nature makes it ideal for fragile surfaces and high-speed machinery.

Many people mistake the growth in capacitive touch sensors as the adoption of new technology. But the fact is advances in mixed-signal programmable devices, those that combine analog and digital into ...

When you look at switching solutions for electronic wearables, your options are limited. With a clever application of conductive fabric and thread, you can cobble together a simple switch, but the ...

We're used to tapping away at flat, glass-covered touchscreen devices like smartphones and tablets. A group of Stanford researchers have taken that capacitive touch concept and applied it to a ...

Apple is examining a shift from a force sensor in AirPods to a capacitive touch system to make a set easier to control, and provide new options. The latest in Apple's surprisingly long history of ...

In touch: John Madden (left) and Mirza Saquib Sarwar with their sensor. (Courtesy: UBC) A flexible touch sensor that can distinguish between being touched and being stretched has been developed by ...

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 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 ...

In the last Sensor Sense we looked at capacitive touch switches used for on/off control. But these switches are also found in capacitive touch sliders that can control various levels, such as volume ...
