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 ...

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 ...

Charge transfer minimizes sense-plate count. Evaluation kits speed robustness and ease-of-use assessment. While electronics engineers struggle to embed more functions into ever-shrinking size and ...

KT Series capacitive touch sensitive sensors are designed to be used as machine start/stop buttons in the industrial automation, mobile and building automation industries. The sensors provide a ...

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.

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 ...

With the introduction of the first smartphones in 2012 with in-cell touch displays, a battle is emerging between the traditional supply chain of ITO-based touch sensors that are externally combined ...

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 ...
