SXSW: Wi-Charge Uses Infrared to Wirelessly Charge Your Devices
On Sunday at the SXSW Innovation Awards Finalist Showcase, Wi-Charge was showing off their infrared-based wireless power technology. They're not the only company aiming to deliver wireless power to our devices, but they are the first we've seen to use infrared (IR) to do it. Using IR comes with a couple of advantages: power doesn't degrade over distance, a thin beam can be aimed at the device to ensure full power, and IR is something we've found to be extremely safe. Of course, the major downside to using IR is that it only delivers over line-of-sight. Their demo at SXSW was delivering a full 1 watt of usable power, but they say their tech could eventually deliver "several watts" of power up to 15 feet away. Wi-Charge was demoing their tech with LED strip lights, an electric train, and a custom-case for an Amazon Echo Dot, all of which could be powered from an overhead IR transmitter. For your IoT devices or even your phone at your desk, this could someday offer a ton of convenience. Wi-Charge is seeking integration partners to help bring their tech to market.
