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 latest generation of handheld personal consumer electronic devices, with their highly sensitive and intuitive user interfaces based around projected capacitive (p-cap) touchscreens, have begun to ...

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 ...

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 ...

Capacitive touch screen technology underpins many modern interactive devices by utilising the inherent ability of certain materials to store and transfer electrical charges. The operation of these ...

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 ...

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 ...

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 ...

Created by ATLab of South Korea, the company is distributing the FMA1127 touch sensor controller that converts capacitance generated by the human body and conductive touch pad to digital data with no ...

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 ...
