SUMMARY:Meander Coil++: A Body-scale Wireless Power Transmission Using Saf

DESCRIPTION:Talks\n\nMeander Coil++: A Body-scale Wireless Power Transmiss
 ion Using Safe-to-body and Energy-efficient Transmitter Coil\n\nKawahara\n
 \nWearable devices for life-logging and healthcare have been studied, but 
 the need for frequent charging imposes inconvenience for long-term use. In
 tegrating textile-based wireless chargers (i.e., coil) into clothing enabl
 es sustainable wearable computing by charging the on-body devices in use. 
 However, the electromagnetic field generated by conventional coil chargers
  strongly interferes with the human body, and the high resistance of condu
 ctive threads leads to inefficient power delivery. This paper presents Mea
 nder Coil++, enabling safe, energy-efficient, and body-scale wireless powe
 r delivery. Meander Coil++ uses a wiring pattern that suppresses electroma
 gnetic exposure to the human body without compromising power delivery perf
 ormance and a liquid-metal-based low-loss conductive cord. With these adva
 ncements, Meander Coil++ transmits a few watts of power to on-body devices
  at 25% DC-to-DC efficiency while complying with international safety guid
 elines regarding electromagnetic exposure. We envision Meander Coil++ can 
 maintain multiple devices on the body for weeks beyond the confines of the
 ir small battery capacity.\n\nRegistration Category: FULL ACCESS, EXPERIEN
