Accelerating the popularization of wireless charging, which enables efficient charging of even metal appliances.
Applicable to home appliances, the Internet of Things, mobile computing, automotive, medical, and industrial fields.

STMicroelectronics (ST) and WiTricity, a pioneer in long-range wireless power transmission, have agreed to jointly develop a semiconductor solution for magnetic resonance wireless power transmission. The goal is to "cut the last wire" and improve charging and power supply convenience for home appliances, IoT devices, as well as medical, industrial, and automotive applications.

The semiconductor solution being jointly developed by WiTricity and ST will be a joint product that leverages WiTricity's intellectual property rights and wireless power transfer mixed-signal IC design technology and ST's strengths in power semiconductor design, manufacturing, packaging, and support.

In the consumer electronics and IoT markets, power transmission and reception systems incorporating this new semiconductor will enable simultaneous wireless rapid charging of multiple devices while also offering greater spatial freedom. Dubbed "Wireless Charging 2.0," this semiconductor solution utilizes magnetic resonance technology and promises unique advantages over existing technologies, such as efficient charging of metal-based smartphones, tablets, and smartwatches.

This product includes a multi-mode solution that integrates resonant and inductive charging methods, as well as a design that complies with the AirFuel™ magnetic resonance specification. The AirFue Alliance is an international organization dedicated to providing the best possible wireless charging experience for appliances. It builds an interoperable ecosystem of wireless charging Power Transfer Transmit Units (PTUs) and Wireless Charging Power Receive Units (PRUs), enabling users to charge their devices anywhere, whether at home, in the office, or in their car.

WiTricity has world-class technology in wireless power for automotive, industrial, and medical applications, as well as the consumer market. ST and WiTricity jointly demonstrated high-power wireless transmission technology at the 2016 Asia-Pacific Economic Cooperation (APEC) meeting in Long Beach, California. For the automotive industry, WiTricity recently announced a wireless "park-and-charge" development kit utilizing its 11kW solution for charging electric and hybrid vehicles. This solution has successfully passed testing by the Society of Automotive Engineers (SAE) for registration as a new global standard.
