Abstract

The integration of energy harvesting technologies with Internet of things (IoTs) leads to the automation of building and homes. The IoT edge devices, which include end user equipment connected to the networks and interact with other networks and devices, may be located in remote locations where the main power is not available or battery replacement is not feasible. The energy harvesting technologies can reduce or eliminate the need of batteries for edge devices by using super capacitors or rechargeable batteries to recharge them in the field. The proposed chapter provides a brief discussion about possible energy harvesting technologies and their potential power densities and techniques to minimize power requirements of edge devices, so that energy harvesting solutions will be sufficient to meet the power requirements.

Highlights

  • The technological advancement in energy-efficient low-power hardware vanquished the need of AC current for Internet of things (IoTs)-based embedded systems, making them suitable for remote applications

  • Energy harvesting technologies together with low-power platforms and energy-efficient storage technologies allow edge devices, IoTs and embedded systems to work in remote areas

  • A report published on energy efficiency of the Internet of things (IoTs) focuses attention on the utilization of edge devices in various applications, and most of these applications are battery driven, which are having limited lifespan (Figure 1)
