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 ...

Capacitive sensors work by using the human body as one of the capacitive plates of an electrical circuit. A leader in low power capacitance touch sensors, NXP offers a range of auto calibrating ...

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 ...

Electronic and Arduino enthusiasts may be interested in a new creation by developer Paul Bartek, who has created an Arduino touchscreen display in the form of the Sunflower Shield. The new hardware ...

Ever wondered how a touch-sensitive screen works? The answer is capacitive sensing, which can detect the presence of your finger through the protective glass sheet and doesn't require any pressure.

Today’s homes and workplaces are increasingly pervaded by smart appliances, which are designed to be attractive and reliable, and ideally should support interactions that are as easy and rewarding as ...

Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level sensing ...

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 ...
