A quantum leap forward in convenience and ease of use for wireless charging of consumer electronics, the WiTricity system charges gadgets over distance and through a variety of materials – including wood, granite, plastic and glass. Initially designed for the iPhone 5/5s, the WiTricity charging system is available as a reference design for companies who want to apply the technology for charging other smartphones, tablets, or consumer electronic devices.
The WiTricity charging system for the iPhone 5/5s includes a wireless charging hub and a charging sleeve that fits an iPhone 5 or 5s. Similar to other protective covers, the WiTricity sleeve quickly slides onto an iPhone 5/5s and is powered when in proximity to the WiTricity charging hub. Capable of charging two phones concurrently, the charging hub can be placed on top of a table as an upright or flat charging pad, or mounted underneath a table or desk for charging through the surface. By mounting the charging pad under a surface, smartphone users are freed from the tangle of charging cords and cluttered desktops.
Traditional inductive charging pads have seen limited acceptance because they require very accurate placement of the mobile phone on the charging pad, while taking up valuable tabletop real estate. In contrast, the WiTricity system provides:
●Positional Freedom: Simply place an iPhone 5/5s in its charging sleeve in proximity to the charging hub and the phone charges as quickly as plugging in. Unlike induction pads, there’s no need to position the iPhone exactly in a specific location on the charging hub.
●Multiple Device Charging: Using a single coil, the WiTricity system allows multiple devices to be charged simultaneously and effectively. With induction-based systems, multiple device charging on a single pad requires multiple coils, driving up the cost of the charging system.
●Installation Flexibility: Unlike induction mats or other chargers that require physical contact and placement on top of a table or other surface – or major modifications to the table or counter – the WiTricity charging hub can simply be affixed under a table while providing power to the phone through the tabletop. Any table, desk, or counter can be turned into a wireless charging “hotspot” without unsightly clutter or requiring drilling or cutting into the underside or through the surface.
“Our team is thrilled to introduce the first wireless charger that works over distance,” said Eric Giler, CEO of WiTricity. “We’ve seen the transformative nature of our foundational highly resonant wireless power transfer technology in the automotive, medical and military fields, and now plan to change the game in consumer electronics. This is an incredibly exciting time for resonant wireless power, and we’re excited to be leading the charge to a wireless future."
WiTricity is not selling directly to consumers, it is merely a proof of concept. It does hope to show off its design to manufacturers to explore with the technology.
