Trial of the External Electric Power Supply-Less IoT System Using Hollow Core Fiber

Wired IoT system without electrical power feeder was examined. An application-driven IoT system using a deep sleep algorithm and high-efficiency Power over Fiber (PWoF) with hollow core fiber was developed and power measurement experiments were conducted. We also verified energy harvesting with PWoF and its ability to drive an IoT system without an external power source. The developed IoT system could be driven once every 16.3 minutes without an external power source, with an average power consumption of 105 mW.
