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 ...

Creating capacitive touch-sensitive buttons is easy these days; many microcontrollers have cap-sense hardware built-in. This will work for simple on/off control, but what if you want a linear, ...

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.

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 ...

Capacitive touch-sensing user interfaces are replacing mechanical buttons in products across consumer, medical and industrial segments. However, with the advent of touch-sensing user interfaces, ...

This article provides an overview of capacitive touchscreen technology and describes the challenges inherent in implementing this technology in handheld devices. Ever since Apple launched the iPhone ...
