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 ...
