Wireless power was pioneered by Tesla a century ago, but it found no commercial applications in the early half of last century. However, it was revived in recent years and its market size is expected to increase from US$ 6.5 Billion in 2018 to over US$ 40 Billion by 2027. This talk will start with a brief historical review of “near-field” magnetic wireless power transfer (WPT) dating back from Nicolas Tesla’s work a century ago. It will clarify that magnetic resonance was pioneered by Tesla in his early work and is not a recent invention. It will also explain why WPT became feasible again since 1980s with some highlights of landmark examples.
The second part of the talk will focus on the latest research and developments of WPT from one-directional to omni-directional applications, with emphases on portable electronics applications. The speaker will address some emerging WPT technologies and applications arising from the merge of the power system infrastructure and information infrastructure.
The speaker will end his talk by addressing the emerging and future trends of WPT technologies and international WPT standards. He will also share his views on the factors that will limit WPT applications.
