Liquid-level sensing is used in consumer electronics appliances like washing machines to detect the detergent level. The sensor technolo­gy has progressed to such an extent that refrigerators can now ...

April 24, 2009 Automatic faucets are a good idea, they're convenient, hygienic and big water savers, but many of us who've encountered these "smart taps" in public washrooms would be familiar with the ...

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 ...

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 ...

The Capacitive Touch Sensor (CTS) is a gesture sensitive functional textile touch-pad interface for physical devices. The CTS is produced as a single piece of fabric requiring only two electrodes to ...

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 ...

Makers and hobbyists that are looking for a capacitive touch sensor for a project, might be interested in a new touch sensor board called the EasyTouch. The EasyTouch capacitive touch sensor can be ...

• 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 ...

This file type includes high resolution graphics and schematics. Capacitive touchscreens have increasingly become mainstream and are no longer a novelty. Their adoption continues to grow as devices ...

I am trying to test a capacitive touch sensor. Specifically, I want to show that it registers a specific change in capacitance. Capacitance is defined as: C = A * Eo * Er / d Keeping A, Eo and d ...
