While thinking about my bathroom mirror light project (https://www.edn.com/elegant-bathroom-mirror-lights/), I was surprised to note that there are many dedicated ...

This is a very simple touch sensor switch that is build with the 555 timer IC. You just need to touch the metal plate and the relay gets energised and is kept in this state for about 100 seconds, then ...

This is a touch sensing circuit based on the principle of capacitive voltage division. It employs differential measurement techniques, which effectively reduce interference from environmental noise, ...

Imagine a bulletproof iPod. It’s possible with new touch sensors that use resonant sound instead of capacitance. • Trapped acoustic resonance is most simply described with an analogy: the ringing of a ...

For CNC machines like VMC (Vertical Machining Center) a regular task is to find the center or an edge of a workpiece as a reference for the following machining. However, this can be extremely annoying ...

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 ...

[Sebastian] is learning Morse code and CW radio, and of course he needed a telegraph key. Instead of using the terribly unergonomic paddle style key, he built a capacitive touch iambic key over the ...

Inspired by the behavior of natural skin, researchers have developed a sensor that will be suitable for use with electronic skin. It can measure changes in body temperature, and react to both sunlight ...
