This PLL-based circuit implements a touch-switch circuit using the PC board or small metal pads as sensors; it is radiometric and thus insensitive to changes in temperature and supply voltage.

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 ...

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 ...

Projected-capacitive touch has grown more than 100-fold in revenue since the iPhone was introduced in 2007, and it shows no signs of slowing down. This article describes many of the design and ...

Nintendo's brand new console-handheld hybrid Switch tablet has a 10-point capacitive touch display that will leverage unique TouchSense tech and software to bring engaging experiences to gamers.

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 ...

You can buy small modules with capacitive touch detection ICs — most often it’s the TTP223, a single-button capacitive model with configurable output modes. These are designed to pair with a ...

The Capacitive Touch Sensor (CTS) is a gesture sensitive functional textile touch-pad interface for physical devices. The CTS is produced as a single piece of fabric requiring only two electrodes to ...
