Optically‐Driven Wireless Microelectronics for IoT and Wearable Biomedical Devices

Abstract

Wirelessly‐operated microdevice technology for informatization of non‐electric objects will be a key breakthrough for advanced IoT framework. In this paper, we identify the requirements for microdevice technology in such applications and explain why an optical power transfer/energy harvesting platform is a promising primary powering option. The architecture and circuits suitable for versatile optical powering/energy harvesting are described and demonstrated. © 2026 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.
