Wireless charging startup uBeam has had a rollercoaster existence. University of Pennsylvania student Meredith Perry founded the company in a garage in 2011 and raised $26 million in funding from investors including Marissa Mayer, Marc Andreessen, and Mark Cuban, who referred to the concept as a \"zillion-dollar idea.\" The company's sound wave-based tech remained secretive. Several investors admitted they'd never actually seen it in action, which fueled suspicion among industry watchers that it might not live up to Perry's promises. <\/p>\n
All the while, Perry stood by her invention. \"We've proved out the technology,\" she said at a conference in May 2016, \"and we are on our way to deploying the product to the world.\" <\/p>\n
Then, the company's former VP of engineering wrote a series of blog posts accusing the company, essentially, of being a fraud. Paul Reynolds, who has 20 years of experience with ultrasound, wrote last year that the company had overstated its technology's capabilities and wasn't close to delivering a working prototype. <\/p>\n
This week, uBeam finally unveiled its technology. The company demonstrated its device for USA Today, according to a report published Thursday, and it worked almost as advertised. With no cables, the company's transmitter was able to charge a phone in a reporter's hand about four feet away. <\/p>\n
The transmitter, a large white box that sits in the middle of a room or can be mounted on the ceiling, emits high frequency sound waves that aren't detectable to the human ear. Those waves are converted into power once they reach a phone, tablet, or other device enclosed in a uBeam case. <\/p>\n
There are currently major limitations, though: The device must be held in the direct path of the sonic beam or it won't charge, and the waves can't pass through walls, people, or other objects, like a pair of jeans. The goal is to eventually be able to charge a phone while it sits in a person's pocket. <\/p>\n
The company has created a second transmitter that uses optical lasers and can charge up to five phones at once, so long as they're held at a 45-degree angle. With both transmitters, the device to be charged must be within about 10 feet. <\/p>\n
In February, Perry showed off the tech's charging capabilities at the Upfront Summit in Los Angeles, though from a distance. This time around, she gave a hands-on demonstration--and beforehand, took the reporter to a T-Mobile store to buy a new phone to prove it wasn't rigged. <\/p>\n
While uBeam still has a lot of development work before it can produce a marketable product, the demo may help the startup get past the intense skepticism it faced just a year ago. Perry wouldn't make any predictions about when it might commercialize its technology, but USA Today reports that it's still at least a year away. <\/p>\n
Perry was frank about how the criticism has affected her. \"As a first-time founder and as a scientist, to have people question your integrity is horrible,\" she told the publication. \"It was extremely painful.\" <\/p>\n
\"In that same week that all that stuff was being said about me, that I was a fraud, we had these big technological breakthroughs,\" she said. \"So I just tried to focus on my team, to keep them going. So we could prove everybody wrong.\" <\/p>\n
The Santa Monica-based company currently has 30 employees. There's a lot at stake: According to Allied Market Research, the market for wireless charging will be $37.2 billion by 2022. <\/p>\n
