As the largest consumer electronics show in the world, CES often gives us a hint of the technologies we can look forward to in the near future, based on the products that are shown off at the show. In 2013 and 2014, there was a heavy focus on wearables, and this year's emphasis on home automation suggests 2015 will be a big year for connected home products.
There's one other important emerging technology that we may see explode over the course of the next few years -- wireless charging. Several companies, including Energous and WiTricity, demoed upcoming wireless charging solutions, and the Alliance for Wireless Power had a booth showing off how wireless charging will work in the Home of the Future.
MacRumors had a chance to sit down with Alex Gruzen, the CEO of WiTricity, who walked us through the company's technology, its existing partnerships, and gave us details on when we might see the debut of the first products using WiTricity's technology, which uses the Rezence specification agreed upon by the Alliance for Wireless Power. WiTricity's wireless charging solutions, which we have covered multiple times in the past, works using magnetic resonance, which is able to transfer power over distances using the magnetic near-field.
In the past, wireless charging solutions like the Powermat (which uses a competing technology from the Power Matters Alliance) have required the electronic device being charged to rest directly on the power source, but WiTricity's wireless charging technology is unique because it does not require direct contact. The magnetic field used for charging is able to wrap around barriers, letting WiTricity charging pads be placed in unassuming locations like under desks, rugs, tables, and more.
In our time at the WiTricity booth, we saw charging pads that were placed under concrete, under desks, and more, hidden out of sight but still capable of delivering a full charge to a device (or multiple devices at once) equipped with WiTricity's technology. This type of hidden charging technology is what we can expect in the future, and Energous, previously mentioned, also debuted a similar "WattUp" technology that uses radio frequencies to charge devices, replacing a charging pad with a transmitter that can provide power up to 15 feet away.
