Energous’s WattUp – Over-the-Air Wireless Charging Technology

Energous’s WattUp – Over-the-Air Wireless Charging Technology

Energous WattUp Wireless Charging Technology devices were revealed in CES 2018 show. The company recently received FCC approval for its first over-the-air, power-at-distance wireless charging technology.

The was embedded in an all-in-one PC could transmit power to multiple devices at up to 3 feet. In this case, it was a mouse and keyboard that were receiving power via built-in receiver. WattUp technology is clever enough to switch between multiple gadgets to they’re always topped off.

Energous even says that its tech is sophisticated enough to support scheduling capability. As the keyboard further moved away, we could see the power output drop from 67 milliwatts down closer to 20 mW. This sort of technology could be embedded into desktops or even laptops within 18 months.

Energous demonstrated output of up to 250 mW at CES, and the WattUp Mid Field transmitter can produce more or less, to support different functionalities and capabilities.

In another Mid Field Demo, WattUp was integrated into a Bluetooth to beam power to a nearby fitness tracker and . This kind of wire-free charging is ideal for smaller devices, and you could place the transmitter on a desk or nightstand.

Energous rep said that the company’s sub-gigahertz technology transmits at well below the SAR (specific absorption rate) for phones, and that its beam-forming technology is precise enough to direct only in the direction of the gadgets being powered. In addition, WattUp will stop delivering juice once your device is topped off.

Next, there was Near Field High Power demo, which delivers closer to 5 watts of juice to a phone. However, in this case the device needed to be placed directly on a base. So while this was indeed wire-free charging, it wasn’t at a distance. Energous says WattUp can go up to 7.5 watts in this configuration. Energous says its solution allows for greater ‘rotational freedom’ over coil based technologies.

At CES 2018, Energous announced a WattUp product available for pre-sale, the Myant Skiin activity tracker, which you can embed in underwear. It also showed off hearing aids from Delight and SK Telesys, though those are not available for order yet.

It is going to take some time for Energous to work with tier 1 device makers to embed its transmitters and receivers, but overall WattUp has the potential to make charging cords a thing of the past.
