Capacitive sensors work by detecting the change of capacitance introduced by the finger touching near the electrode. Such change is so small that detecting it unambiguously is challenging, and has ...

It is not straightforward to design the layout for capacitive sensors and still achieve a 5:1 SNR in the end system. This is further complicated when using an MBR device where developers don’t have ...

If you have a project in mind that requires some sort of gesture input or precise movements, it might become a nettlesome problem to tackle. Fear this obstacle no longer: a team from the Wyss ...

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 ...

Two tiny ICs and a few passive components can yield a capacitive proximity sensor with excellent sensitivity and extremely fast response time. The circuit’s operation leverages the pulse-front-edge ...

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 ...
