Wireless Charging RF and Audio


Recommended Posts

Wireless charging via Bluetooth LE is likely coming to all our mobile and IOT devices. Energous (developer of WattUp) just got a $10 million investment from Dialog Semiconductor. There have been indications that Apple is evaluating this technology for inclusion in its products.

 

It will be interesting to see whether doing power distribution over the air introduces any new challenges for audio.

Energous stock was up nearly 75% after hours today.  The FCC has certified its wireless transmitter which can charge devices like smartphones via RF from up to 3 feet away.

This technology may be more important in public places like coffee shops and airports than at home.  It makes more sense than wireless charging pads which need to be plugged in. 

 

Ultimately, the goal is to never need to think about your device running out of juice.
