Capacitive touch switches work by measuring the change in capacitance of a PCB (printed-circuit-board) pattern depending on the placement of a user’s finger over a sensing pad. Capacitive switches are ...

Capacitive touch sensors are based on the electrical capacitance of the human body. When, for example, a finger comes close to the sensor, it creates a capacitance to Earth with a value of 30 to 100 ...

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.

EBE sensors + motion is expanding its portfolio of capacitive input systems for industrial control concepts with the TCRC.

We're used to tapping away at flat, glass-covered touchscreen devices like smartphones and tablets. A group of Stanford researchers have taken that capacitive touch concept and applied it to a ...

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 ...

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 ...
