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 ...

Capacitive sensing has emerged as a promising non-contact approach for acquiring biopotential signals such as electrocardiograms and electrodermal activity. Unlike conventional methods that rely on ...

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 ...

Anyone who has tried to troubleshoot an interference problem knows it can be a lot like chasing ghosts. Just about the time you think you have it, all trace of it disappears or, worse yet, the ...
