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 ...

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 ...

ワコムは23日、同社独自の表面静電結合方式タッチセンサー技術「Reverse Ramping Field Capacitiveタッチ」を発表した。出荷は7月〜9月期に開始される予定だ。 Reverse Ramping Field Capacitiveタッチは、コンピュータ機器のスクリーン表面に組み込むことでこれらの機器を ...

When you look at switching solutions for electronic wearables, your options are limited. With a clever application of conductive fabric and thread, you can cobble together a simple switch, but the ...

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 ...

3M Touch Systems announces the commercial availability of a new polyester-based projected capacitive touch screen solution. MicroTouch Flex Capacitive Touch Sensors from 3M are ideal for high-volume ...

Infineon has introduced automotive microcontrollers with capacitive touch sensing for sensor and actuator applications. The PSOC 4 HVMS family is built around a 24 or 48MHz Arm Cortex-M0+ processor, ...

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 ...
