Wireless Charging

If this startup has its way, we’ll always be fully connected — and fully charged.

January 2015


It feels like science fiction, but two University of Pennsylvania graduates have created a device that could eliminate the need to plug in our smartphones, laptops and tablets. Their company, uBeam, uses a patented ultrasonic transfer method — sound waves — to transmit power over the air. Attach a tiny uBeam receiver to your device and you can charge up on the go. The technology remains in its infancy, but uBeam has picked up more than $3 million in early-stage funding, and it promises to have products on market shelves within two years.
