Capacitive-touch sensors can detect a finger touch by measuring capacitive changes on the touch pad. Currently, the most popular form of capacitive-touch sensors relies on a microprocessor and ...

Creating capacitive touch-sensitive buttons is easy these days; many microcontrollers have cap-sense hardware built-in. This will work for simple on/off control, but what if you want a linear, ...

In Part I of this series, we explored the differences between user interfaces based on mechanical buttons and those utilizing capacitive touch sensors. In Step 1 we discussed the look and feel of a ...

Before the introduction of the iPhone X and Face ID, Apple was considering ways to implement Touch ID on a smartphone without using an externally visible fingerprint reader, with one technique ...

The touch sensors on smartphones and tablet computers allow people to sling angry birds across the screen or scroll through pages of cat pictures with a gentle finger swipe. To detect a user’s touch, ...

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 ...
