Wireless power transfer has the promise to eliminate power cords and radically change how we interact with electronics. However, previous approaches fail to embody this vision because it is challenging to achieve "high-power" and "wide-range" power delivery at once. This talk will introduce our recent magnetoquasistatic wireless power projects, achieving safe and efficient delivery of large amounts of power within large volumes. Our studies are inspired by various electromagnetic systems such as cavity resonators and metasurfaces and explore the interdisciplinary domain between such electromagnetic technologies, ubiquitous computing, and human-computer interaction.
