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.

Now that we have discussed the theory about the sigma-delta modulator, let us design a simple proximity sensor that will detect an approaching hand and switch on an LED. A 0.5 mm 2 wire, 10 cm long, ...

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 ...

Why auxetic materials offer some unique advantages in sensor fabrication. How additive manufacturing was used with autextic materials to create unique pressure and force sensors. The structure and ...

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 ...
