Distributed micro-energy harvesting for next generation of IoT in various scenarios

Abstract

Abstract Recently, internet of things (IoT) attracts increasing attention and it tends to be applied in every aspect of life, due to the development of computer technology, sensor technology and micro/nano technology. Although IoT plays an important role in modern society to achieve smart life, it has to overcome the restriction of non-durable power source and to construct wireless sensor networks. Micro-energy harvesting technology from the environment is a powerful and promising approach to solve the energy supporting problem for wider applications of IoT. This article gives an overview of the recent developments of self-sustained IoT from the perspectives of energy harvesting technology and related technologies. The various energy harvesting techniques and the applications of IoT in different scenario are collected and presented. The energy schemes to prolong and optimize the energy in the WSN for IoT are discussed. Furthermore, perspectives and outlooks of self-powered IoT based on the micro-energy harvesting technology are presented.
