About awarded research Wearable devices with small battery capacity are difficult to use for long time and have limited functions. Although a cloth-type wireless charger has the potential to stably power up functional wearable devices in the use, the electromagnetic field exposure in the body limits the power transmission amount, and the high loss of conductive yarns results in low power transfer efficiency. Therefore, we first improved a meander coil that we previously developed for wireless communication to efficiently power up the devices near the body surface while suppressing electromagnetic field exposure. Then, by using flexible liquid metal wires, we realized a safe and efficient wireless charging system capable of supplying 2.5 W of power with an efficiency of about 40%.
Your impression & future plan We are very honored to receive this award. We would like to thank all of our collaborators who have worked with us on this challenging research and who have supported us in our research life. We hope this paper will contribute to the future development of wireless charging.
