Energy Harvesting and Power Management for IoT Devices in the 5G Era
Prospective energy harvesting scenarios of IoT devices in the 5G network
“The fifth generation (5G) network is a rapidly growing technology that is impacting personal devices for both society and the economy. With the pervasiveness of Internet of Things (IoT) devices in these networks, powering and exploring the energy to operate them is vital in the 5G era. Therefore, the projection and forecasting of how to power IoT devices in the 5G network has already begun, with the aspiration of providing future self-powered and green communication services. Here, we offer a view of energy harvesting technologies for IoT devices (e.g., emerging wearable and implantable devices used in healthcare and consumer technologies) that can help the research line in the age of 5G. We propose that various techniques for harvesting and managing energy at the circuit, device, and system level will constitute the most crucial segment of IoT devices. Thus, self-powering and durability should be key characteristics of IoT devices in the 5G network, and should receive special attention from the electronics and communications communities. To consider this concept, we provide a systematic overview in which the prospective energy harvesting scenarios of IoT devices in the 5G network are expected. We successively describe the vital potential landscapes of 5G and assess the requirements for energy harvesting and energy management. We are also exploring challenges beyond energy technologies that could impede 5G improvement.
