Mobile devices such as tablets and cellphones generally require proximity sensors for Specific Absorption Ratio (SAR) qualification and on-ear detection. Capacitive sensing may be used to meet both of ...
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 ...
In many electronics products such as consumer, home appliance, automotive, industrial etc., capacitive touch buttons are fast replacing traditional mechanical buttons. Although capacitive buttons have ...
This file type includes high resolution graphics and schematics. Capacitive sensors are common in today’s consumer electronics, since they are used in many touchscreen applications. Most of the ...
Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level sensing ...
