If uBeam has its way, dead batteries and charging cords will soon be a quaint memory, much like rotary dial telephones.

Meredith Perry, who began tinkering with wireless charging as a paleobiology undergrad at the University of Pennsylvania, started the company in 2011. "Just think of my grandpa, who could have his pacemaker powered remotely, or my other grandpa, who can't hear if he forgets to change his hearing-aid battery," she notes of the technology's broad potential.

Areas where uBeam could reshape business include powering tablets at retail, wireless headsets at warehouses, battery-powered tools at construction sites—devices would always be charged and ready to go.
