Radient to ‘recycle wasted RF waves’ to recharge your battery Featured

By

Imagine if your smartphone or tablet battery was smart enough to recharge itself using power from the radio waves it generates to go online. Radient says it can be done!

Radient Micro-Tech. It’s a company I’ve never heard of before, and chances are good that you’ve never heard of it either.

However, the company says it has "received two key patents for its groundbreaking technology that captures RF waves and converts them into electrical energy for reuse and/or charge cell phones and other electronics".

Radient proudly boasts that "is the first company to patent the concept of repurposing the cell phone's surface into an energy-harvesting antenna that absorbs and reuses its own wasted radiated power to deliver smarter, green wireless charging".

It makes you wonder whether phone companies, with all their phone towers, might be able to make use of such technologies to extend the life-span of their tower’s battery back-up systems when power outages occur, or where else such radio wave energy harvesting technology could be applied.

Indeed, the technology reminded me of Ossia’s wireless power technology that promises to keep all of the batteries in your devices wirelessly recharged without charging pads but in the same wireless way your devices operate over Wi-Fi.

After all, if you had to place your smartphone or tablet on the router for it to be "wireless", it wouldn’t be much of a wireless revolution.

I video interviewed an Ossia executive on the company’s groundbreaking technology late last year. 

So, just like Ossia promises to be revolutionary, so too does Radient’s amazing sounding technology, too.

Radient notes that "mobile devices require a tremendous amount of power to send signals to cell towers, but only a tiny portion of this energy ever reaches the intended target and up to 90% dissipates into the air".

This company says its technology "collects that radio power and uses it to extend the battery of the cell phone", reducing "power consumption and improves battery life by up to 30%".

Radient continued, stating: "This not only creates a better experience for consumers, but also reduces the cost and size of the battery, resulting in huge savings for device manufacturers. Additionally, Radient's patented technology serves as a wireless charger that enables users to power up on-the-go rather than tethered to a table, representing a decisive competitive edge for the manufacturers that implement it."

Again, it sounds a little like the type of technology that Ossia has developed, although quite different at the same time.

Radient states that: "Wireless charging is something mobile device users have wanted for years, according to a report from research firm IHS. Running out of battery, misplacing or forgetting cords, and untangling wires are frustrations that most mobile users deal with on a regular basis. Better battery life and wireless charging are clearly the way of the future, but turning this vision into a reality has been a slow process."

Radient co-founder and chief technology officer Marc Chen said: “Most of the options out there today transfer power from one location to another — from charger to device — a principle that Nikola Tesla demonstrated back in the 1890s. Radient is the first company to go beyond this outdated, 19th century model.

"In addition, poorly designed externally attached cell phone case solutions can degrade or block a cell phone's communication signal, creating a situation where in an emergency, calls will be dropped. Radient has developed the technology to specifically address these kinds of problems."

Radient says it will "license its smarter, greener wireless charging technology to wireless device manufacturers, wireless charger manufacturers, and semiconductor suppliers who will benefit from cost savings ($0.5-$1.00 battery cost savings per phone) and a competitive edge".

For large cell phone companies that sell 50-300 million phones per year, Radient says its "technology translates into huge annual cost savings, while for smaller companies, offering 'Smarter, Greener Wireless Charging' can help increase revenue at $100-$600 per additional phone sold".

And, by incorporating Radient's technology, the company says "existing wireless charger companies can instantaneously leapfrog their competition by wirelessly charging for free".

Chen added: ”The two patents represent a powerful foundation and are just the beginning for Radient. We are expanding our patent portfolio and continue adding breadth to our offering, setting the business up to deliver valuable technology for a long, long time."

At Radient Micro-Tech’s site, the company also boasts that it has "Applications beyond Phones", and says that "the technology can also be easily applied for specialised communication equipment such as Military and EMS communication Radios", and adding that "we can even harness the switching energy generated by PCs and servers to reduce their power consumption".

So, a wonderful wireless future awaits. I can’t wait to "plug" into it!
