Global semiconductor leader STMicroelectronics Pty Ltd is partnering with WiTricity to develop semiconductor solutions for magnetic resonance-based wireless power transfer. WiTricity is the industry pioneer in wireless power transfer over distance. A key objective of the design collaboration is to bring convenience to the powering and charging of consumer electronics, Internet of Things (IoT) devices, as well as medical, industrial, and automotive applications.

The new semiconductor solutions will leverage WiTricity’s foundational intellectual property and wireless power transfer mixed-signal IC design expertise as well as ST’s leadership in power semiconductor design, fabrication and packaging capabilities. Consumer electronics and IoT markets will benefit from the spatial freedom as well as wireless fast charging of one or more devices at the same time using power transmit and receive systems built with these new semiconductors.

The new semiconductor solutions, referred to as ‘Wireless Charging 2.0’ built with magnetic resonance technology will also have unique advantages over the current technology, including being able to efficiently charge metal body smartphones, tablets and smartwatches.

Designs that comply with the AirFuel magnetic resonance specification as well as multi-mode solutions incorporating both resonant and inductive charging are being planned as part of the new offerings. The AirFuel Alliance is a global organisation dedicated to delivering the best wireless charging experience for consumer electronics.

Matteo Lo Presti, Vice President and General Manager, Analog, in the Analog and MEMS Group, STMicroelectronics explains that the efficient wireless charging solutions based on game-changing technology from the ST and WiTricity collaboration will increase convenience and ease of use while delighting consumers. It will also enable product designers across the globe to go wireless, allowing ST to promote a broader set of their own semiconductor offerings into these emerging markets.

Alex Gruzen, CEO of WiTricity adds that ST’s vast experience in semiconductor design and fabrication, as well as its access to leaders in the consumer electronics, automotive and industrial markets, will help place WiTricity in a strong position to accelerate the adoption of resonance-enabled wireless charging.
