Wireless Power Transfer Technology | ASTRI - Hong Kong Applied Science And Technology Research Institute Company Limited

Wireless Power Transfer (WPT) means transferring electrical energy from the power source to the electrical device for charging of the battery and/or supporting the device operation without wire or conductor, by using magnetic field coupling which includes Magnetic Inductive Coupling and/or Magnetic Resonant Coupling. In general, all radio wave broadcasting system can be regarded as a kind of wireless energy transfer, but in WPT, the “power level” and “transfer efficiency” are much higher.

ASTRI has developed the medium-range power transfer solution based on the magnetic coupling resonance theory. Our WPT system has a performance of transmitting power higher than 33W at up to 15cm and supporting the charging of multiple devices simultaneously. It can serve as the wireless power transfer technology platform for various electronic products and applications.

Features

Medium charging range (up to 7~8 times of coil diameter)
Flexibility in position alignment
Multiple device simultaneously charging
High safety, non-radioactive and low inductive heat generation

Applications

Consumer Electronics, Smart Home, Sensor and Actuators, etc.
Others, e.g., Robotics, Electric Vehicle, Military, Unmanned Boat & Underwater Vehicle, Implanted Medical Devices, etc.

More about ASTRI

Hong Kong Applied Science and Technology Research Institute (ASTRI) is founded in 2000 by the Government of the Hong Kong Special Administrative Region. As Hong Kong’s largest government-funded research and development centre, ASTRI is a key force and super connector driving innovation and technology advancement in Hong Kong, the Greater Bay Area, and the global innovation ecosystem. This role is strengthened through its merger with Nano and Advanced Materials Institute (NAMI).

Committed to bringing high impact research from lab to market, ASTRI advances interdisciplinary, market driven R&D that delivers practical innovations for industry and meaningful benefits for society.

Its technological strengths and capabilities enable AI powered, cross disciplinary ICT and advanced materials solutions across Smart City, FinTech, Digital Health and Life Sciences, New Industrialisation and Intelligent Manufacturing, Application-Specific Integrated Circuits (ASIC) and Advanced Electronics, New Energy and Energy Storage, and Green and ESG Technologies.

Over the years, ASTRI has cultivated a strong pool of I&T talent and earned numerous international awards for its pioneering innovations and contributions to industry and the community. Following the merger with NAMI, ASTRI’s cumulative patent portfolio has grown to over 1,500, with more than 2,200 technologies successfully transferred to industry.

With enhanced scale and capabilities, ASTRI is uniquely positioned to elevate Hong Kong’s innovation capacity, accelerate technology commercialisation, and drive societal and economic progress through world class applied research.
