uBeam defends its wireless power tech by publishing its secrets


It is not often that one runs across technology that can fundamentally change the way we interact with our devices in everyday life so when it happens, critics and skeptics usually voice their concerns quite loudly. The people behind uBeam know this feeling quite well as their ultrasound-based wireless charging tech has already faced a fair amount of scrutiny despite the fact that almost no one has tried it out yet.

In order to defend itself, uBeam has now declassified a lot of the secrets behind its tech so that experts and laymen can take a look and decide whether this is all cloud-talk or real, plausible tech. For instance, we can now confirm that uBeam works with multiple devices, that it aims to deliver a minimum of 1.5 watts of electricity and that it uses a high-powered air-coupled ultrasonic transducer to deliver and receive sound waves in the 45kHz-75kHz range with an output of 145dB to 155dB. The company covers all that with more than 30 filled patents and 6 issues ones which include core tech developed in-house.

The general population will not really care about these technical details but at this point, uBeam cares more about appealing to big names in tech as well as small business owners as part of its wider launch campaign plan. The company wants to partner up with all kinds of firms so that its technology can be installed in various locations such as hotels and cafes with the hope of being everywhere at some point. After all, the company’s goal is to rid the world of cables so it needs to spread out as much as possible.

Even as a generic concept, wireless power has been the subject of much controversy ever since Nikola Tesla first experimented with the technology before the dawn of the 19th century. But uBeam’s technology is not just a concept and CEO Meredith Perry has not wasted the sizeable investments made in her company. Cynicism and skepticism have their place but not when they are used to stagger innovation instead of promoting better research and more open discussions. I too am weary of getting too excited about uBeam but I do hope that it manages to deliver on its (many) promises.
