RF Energy Harvesting - Review of e-Peas 2.4 GHz energy harvesting evaluation board

Is RF energy harvesting viable to power an IoT sensor? Vast armies of sensors are crucial to feeding IIoT monitoring and analysis applications. Powering these edge nodes is increasingly a channel. Even though modern microcontrollers exhibit ultra-low power consumption characteristics, a battery would need to be replaced at some stage, the total cost of which is typically more than the sensor. Provisioning line/mains power infrastructure is equally expensive. How about energy harvesting? Could this provide a viable power source? What about harvesting ambient RF energy? In this video, we investigate the potential for powering IIoT sensors using this approach.
