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 ...

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 ...

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 global capacitive sensors market is witnessing significant expansion, driven by the increasing adoption of multi-touch capacitive sensing technology in consumer electronics, automotive, and ...

3M Touch Systems announces the commercial availability of a new polyester-based projected capacitive touch screen solution. MicroTouch Flex Capacitive Touch Sensors from 3M are ideal for high-volume ...

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 ...

There are few things more frustrating than being in the middle of working on a project and realizing that you are missing some crucial component that ties the whole thing together. According to Murphy ...

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 ...

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 ...
