Digital IR proximity sensing module shrinks always-available earbuds
Believed to be the smallest digital proximity sensor module, the TMD2635 from ams occupies 1.0mm3 for a form factor that enables manufacturers of true wireless stereo (TWS) earbud products to develop smaller, lighter industrial designs. The IR proximity sensor enables wireless earbud in-and-out of ear detection to help extend battery life between charges and can be used in tandem with another TMD2635 to enable elementary touchless gesture control without the need for buttons.
