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 ...

In Part I of this series, we explored the differences between user interfaces based on mechanical buttons and those utilizing capacitive touch sensors. In Step 1 we discussed the look and feel of a ...

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 ...

Unlock the power of touch! In this deep-dive tutorial, we’re moving beyond clunky mechanical switches and harnessing the ...

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 ...

The multi-touch ClearPad 3000 series of capacitive touch sensors brings high-resolution capacitive touchscreens with basic gesture capability to mobile handsets and other handheld devices. With the ...

The QST108 is the first in a series of capacitive touch sensors from STMicroelectronics using a pure digital, firmware-based solution that implements the Quantum Research Group's patented ...

GOTHENBURG, Sweden--(BUSINESS WIRE)--Fingerprint Cards AB (Fingerprints™) today announces the launch of a new slim and curved capacitive touch sensor for biometric authentication. Following the ...

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 ...

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 ...

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 ...
