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 ...

Capacitive-touch sensors can detect a finger touch by measuring capacitive changes on the touch pad. Currently, the most popular form of capacitive-touch sensors relies on a microprocessor and ...

Ever thought of using touch sensors on your projects but didn’t because it would be too much work? [Paul Stoffregen] proves that it can be pretty easy if you use the CapSense library for Arduino. Here ...

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 ...

The What: Zytronic has unveiled a new version of its rugged, customized touch screens is now available to support secure PIN entry applications via its development partner, Cryptera. The new PCI PTS ...

Before the introduction of the iPhone X and Face ID, Apple was considering ways to implement Touch ID on a smartphone without using an externally visible fingerprint reader, with one technique ...

Capacitive sensors are found in a wide range of equipment, from consumer electronics to industrial/process control. Touch buttons are increasingly found in lamps and dimmers. Motion detectors can ...

You don’t have to have high-quality parts to play around with electronics and here’s a great example. [Vishal] used junk to play around with CapSense, the touch sensitive Arduino library. What he ...
