Capacitive touch sensing allows for triggering the sensor without actually physically touching one’s lips to the electrodes, which [Nathan] did by putting a clear plastic layer over the PCB traces.

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 ...

It’s a force sensor, a pressure sensor, and a switch, all made completely out of fabric. The design of this fabric touch sensor is based around a non-woven resistive fabric made by Eeonyx.

A finger-heating effect has been observed on mutual capacitive touch sensors with plastic film overlay. The symptom is exhibited as serious sensitivity degradation when there is a greater than 10°C ...

As oscillation amplitude falls below the threshold, the level detector turns the sensor output off. Conductive targets affect capacitive sensors as well, but in a different way.

Proximity sensor Two tiny ICs and a few passive components can yield a capacitive proximity sensor with excellent sensitivity and extremely fast response time. The circuit’s operation leverages ...

Capacitive Touch Sensors 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 ...
