picoRing dual: ultralow-power bimanual ring controllers for everyday AR
Hideaki Yamamoto, Yifan Li, Yoshihiro Kawahara +1
Advances in smart eyewear, such as AR glasses and HMDs, bring digital information into outdoor and public situations. However, traditional handheld controllers for hand interaction…
3D-Printing Water-Soluble Channels Filled with Liquid Metal for Recyclable and Cuttable Wireless Power Sheet
Takashi Sato, Ryo Takahashi, Kento Yamagishi +6
A recyclable and cuttable wireless power transfer (WPT) sheet is proposed, enabled by H-tree wiring and water-soluble channels filled with liquid metal (LM). Conventional 2D WPT sy…
Body-scale NFC for wearables: human-centric body-scale NFC networking for ultra-low-power wearable devices (Demo of UTokyo Kawahara Lab 2025)
Hideaki Yamamoto, Yifan Li, Wakako Yukita +4
Near Field Communication (NFC) is a promising technology for ultra-low-power wearables, yet its short communication range limits its use to narrow-area, point-to-point interactions…
Hierarchical resonators for localized charging in room-scale magnetoquasistatic wireless power systems
Takuya Sasatani, Alanson P. Sample, Yoshihiro Kawahara
Magnetoquasistatic wireless power transfer can deliver substantial power to mobile devices over near-field links. Room-scale implementations, such as quasistatic cavity resonators,…
Patched-Wall Quasistatic Cavity Resonators for 3-D Wireless Power Transfer
Takuya Sasatani, Yoshihiro Kawahara
Traditional wireless power transfer (WPT) systems are largely limited to 1-D charging pads or 2-D charging surfaces and therefore do not support a truly ubiquitous device-powering…
Full-body WPT: wireless powering with meandered e-textiles
Ryo Takahashi, Takashi Sato, Wakako Yukita +3
We present Full-body WPT, wireless power networking around the human body using a meandered textile coil. Unlike traditional inductive systems that emit strong fields into the deep…
