Low-Power Radio-Free Sensor System based on Li-Fi and Optical Wireless Power Transfer

This work demonstrates a self-sufficient health and usage monitoring system (HUMS) without any wired or RF-based communication and power transfer. Instead, the wireless, radio-free (WRF) system uses optical wireless communications (OWC) and optical wireless power transfer (OWPT) optimized for a user-friendly operation. The system is capable of live data streaming and long-term data-logging.
