You can’t have a touch sensitive switch without a way to detect the presence of a finger! A touch sensor, especially a capacitive touch sensor, has some surprisingly sophisticated electronics to ...

The QST108 is the first in a series of capacitive touch sensors from STMicroelectronics using a pure digital, firmware-based solution that implements the Quantum Research Group's patented ...

Charge transfer minimizes sense-plate count. Evaluation kits speed robustness and ease-of-use assessment. While electronics engineers struggle to embed more functions into ever-shrinking size and ...

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

KT Series capacitive touch sensitive sensors are designed to be used as machine start/stop buttons in the industrial automation, mobile and building automation industries. The sensors provide a ...

While Apple's most recent innovations have come from portables like the iPad Air and iPhone 5s, a document uncovered on Thursday reveals a feature-laden keyboard with multi-function "keystacks" that ...

• Trapped acoustic resonance is most simply described with an analogy: the ringing of a bell. • Microprocessors control the frequency of the mechanical resonance and monitors its decay. • A thicker ...

Touch display solution provider General Interface Solution (GIS) will have its new plant in Taichung, central Taiwan, come online mainly for producing capacitive fingerprint recognition solutions in ...

Most proximity sensors use an electromagnetic field to sense the presence of a target metal. But there are times when it's necessary to sense nonmetallic materials such as plastics, liquids, or ...

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 ...

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 ...

You can buy small modules with capacitive touch detection ICs — most often it’s the TTP223, a single-button capacitive model with configurable output modes. These are designed to pair with a ...
