Charge your phone using only radio waves.

Charge your phone using only radio waves

The perfect wireless power transmission that charge your phone, without cords or charging mats, has been a white whale for the technology industry for decades. 

But a new startup born from the California Institute of Technology claims how to make it small, cheap, and commercially efficient enough to overcome it. The company has created a wireless charging system that delivers electricity using high-frequency radio waves, specifically the millimeter wave (mmwave) variety that bury 5G cell networks in the US, says Guru.

At the CES next Woche in partnership with electronics manufacturers, Guru will be presenting three charging prototypes. All three prototypes are equipped with a desk charging system that can charge any gadget within just a few meters of wirelessly; a room-sized version that has a far wider range of ceiling tiles; and a rotating robot that is designed to move across a large area; and small, smart home-style appliances such as cameras and IoT sensor systems.

“Nikola Tesla also had the same idea that electricity should be sent wirelessly” says Florian Bohan, co-founder and CEO, who previously founded a cellphone component company called Axiom Semiconductor and uses one to use solar energy. Caltech worked on the initiative and irradiated the Earth using microwaves. 

mmWAVE:

Millimeter wave is an undeveloped band of spectrum that can be used in a wide range of products and services such as high-speed, point-to-point wireless local area networks (WLANs) and broadband access. … IEEE Wi-Fi will run on standard 802.11ad 60 Ghz millimeter wave.

Wireless power transmission, as a concept, is over a century old, and scientists have proven that it actually works, for experiments over the last few decades that have used more sophisticated radio technology. For the tech industry, over-the-air wireless charging for consumer gadgets has been hitting around for some time.


A troubled in startup is trying to use ultrasonic waves for wireless power transmission and has repeatedly worked The product misses its deadline to deliver. Apple recently filed a patent for this exact technology, and many other startups have come to CES in the past years or are planning to come to this year’s show to prove they have the there idea is a working version.


But why should we take Guru seriously? According to Bohan, the company has two advantages. One is that it is using mmWave, which are extremely high frequency radio waves that allow high precision. In this way, the master’s charger can identify the device that needs to be charged and send a local beam of radio waves that transmit electricity, in a way that is superior to low-frequency waves.


But the real innovation guru claims that it is a pioneer that the company calls Smart RF Lining. Ali Hazimiri, co-founder of Bohn, a patented technology developed at CalTech with Kaushik Sengupta of Princeton University, involves controlling the direction and number of beams that receive directions.


Effectively, smart RF licensing allows the master to send multiple beams of energy to small receivers, which allows the transmission devices to fit enough on your desk or shrink enough to be wall mounted. This allows the Guru’s system to charge as small as a cellphone, and even smaller IoT and smart home devices.


But does it really work? I saw a live performance on a video chat of Guru’s system in action, and it served as an advertisement. A member of Guru’s team switched off the desk system, which looks like a large heat lamp, activating a lightbulb sitting a few feet away. When the employee put a hand between the two items, the lightbulb went off. The same was true of a room-scale charger and roaming romba-like one, which would go up to a light switch and activate it automatically after being sufficiently closed.


But the Guru’s vision is little compared to just finishing the cords. Bohn and his co-founders are convinced that, if done right, a proper system for wireless power transmission can not only make changes, but we think about keeping the devices charged and operating at all times. 


There are also types of devices that we use and what those devices are used for. Gurus are envisioning a world where you can live in battery-powered gadgets, big and small, in every corner of your home or office, store, or warehouse, without worrying about whether Where they draw power from or for how long. It stays on a charge. Because to keep everything on top, electricity will flow in the air all the time, just as Tesla did more than 120 years ago.


“The battery really is basically the capacity of your device,” says Hajimiri. “You have to live long, but once paying becomes ubiquitous, it can all shift.”
