The latest generation of handheld personal consumer electronic devices, with their highly sensitive and intuitive user interfaces based around projected capacitive (p-cap) touchscreens, have begun to ...

Capacitive displacement sensors turn tiny gaps into actionable signals. By measuring changes in capacitance as target moves, these devices deliver precise, non-contact readings of position and motion.

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 ...
