San Jose, Ca. – Atmel Corporation has just released to volume production its new maXTouch family of capacitive touchscreen controllers, capable of supporting an unlimited number of unique simultaneous ...

Electromechanical switches are simple, cheap, and widely available (Fig. 1). However, they’re also plagued with a number of disadvantages, including wear with repeated use, and the potential for ...

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 ...

A finger-heating effect has been observed on mutual capacitive touch sensors with plastic film overlay. The symptom is exhibited as serious sensitivity degradation when there is a greater than 10°C ...
