[Bertho]’s submission for the 74xx logic contest is really impressive. He designed a capacitive sensing touchpad using only 74xx and 40xx logic chips. We’re impressed with the build and his writeup is ...

Capacitive sensing as a user input medium is no longer a fringe technology relegated to select products. It is now a mature technology employed in thousands of products and millions of units.

Non-contact displacement measurements can be made rapidly and with high precision using capacitive sensors over a modest range. The main features are: Capacitive sensing is a non-contact measurement ...

The following guide provides a review of the types of proximity sensors for prolonged detection, followed by a look at capacitive sensing design specifically for occupancy-type solutions. A variety of ...

PI (Physik Instrumente) offers a new brochure on capacitive nanometrology displacement sensors and signal conditioning electronics. The brochure presents PI’s sensor systems and also features a ...

There are few things more frustrating than being in the middle of working on a project and realizing that you are missing some crucial component that ties the whole thing together. According to Murphy ...

Adding capacitive sensing to a consumer or industrial product can be a daunting challenge that requires developers to maintain sensor robustness and responsiveness while minimizing current consumption ...

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...
