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 ...

Capacitive touch sensors have made homes i n scores of MP3 players and mobile phones. Of course, the mobile arena is no longer the only bastion for these devices. Today, sensor technology has ...

EBE sensors + motion is expanding its portfolio of capacitive input systems for industrial control concepts with the TCRC.

There seems to be nothing a 555 can’t do. We’ve seen it before, but [electronzapdotcom] reminds us you can use a 555 and a few parts to make a reasonable touch switch in this video, embedded below.

This schematic diagram is about touch switch circuit. Separate ON and OFF switch improves the ergonomics for safety, since the touching off button when the state is off doesn’t make the system acts in ...

TL;DR: The USPTO granted Apple several patents this week. A touch interface that covers the entire device is one of the more intriguing ones. The concept would use touch sensors embedded in the ...
