An Exhaustive Analysis of Energy Harvesting Absorbers and Battery Charging Systems for the Internet of Things

Abstract

Nearly all application fields are paying increased attention to the internet of things (IoT). Nearly 20 billion devices are now linked to the internet. With several applications ranging from smart buildings and smart cities to smart devices, IoT has progressed over the last few decades. As a result, the quantity of sensors, sensor nodes, and gateways has increased, making these battery-powered devices power-hungry. It will be a laborious operation to change the battery in remote monitoring applications for these smart sensors or nodes. By gathering RF energy from the environment and converting it to DC power, RF energy harvesting is a cost-effective method of extending the lifespan of wireless sensor networks (WSNs). A brand-new, IoT-based smart universal charger is suggested in this chapter for charging multichemistry batteries. The suggested charger has an advantage over traditional chargers since it can charge both already installed batteries and any future batteries.
