Abstract
In the recent few years, due to its significant deployment to meet global demand for smart cities, the Internet of Things (IoT) has gained a lot of attention. Environment energy harvesting devices, which use ambient energy to generate electricity, could be a viable option in near future for charging or powering stand-alone IoT sensors and electronic devices. The key advantages of such energy harvesting gadgets are that they are environmentally friendly, portable, wireless, cost-effective, and compact. It is significant to propos and fabricate an improved, high-quality, economical, and efficient energy harvesting systems to overcome power supply to tiny IoT devices at the remote locations. In this article, various types of mechanisms for harvesting renewable energies that can power sensor enabled IoT locally, as well as its associated wireless sensor networks (WSNs), are reviewed. These methods are discussed in terms of their advantages and applications, as well as their drawbacks and limitations. Furthermore, methodological performance analysis for the decade 2005 to 2020 is surveyed in order to identify the methods that delivered high output power for each device. Furthermore, the outstanding breakthrough performances of each of the aforementioned micro-power generators during this time period are emphasized. According to the research, thermoelectric modules can convert up to 2500×10^(-3) W/cm^2, thermo-photovoltaic 10.9%, piezoelectric 10,000 mW/cm^3 and microbial fuel cell 6.86 W/m^2 of energy.

Highlights
Machine to Machine (M2M) communication with little or no human intervention is becoming more and more common
From 2005 to 2020, this research looked at how to improve the performance of four different types of micro-scale energy harvesting devices in order to supply power to Internet of Things (IoT) sensors: thermoelectric, thermo-photovoltaic, piezoelectric, and microbial fuel cells
This study provides a comprehensive analysis of a wide range of promising environmental energy harvesting techniques to power standalone IoT-equipped sensor
Summary
Machine to Machine (M2M) communication with little or no human intervention is becoming more and more common. Applications for M2M communications and the IoT include smart grid automation, healthcare, agricultural systems, transportation systems, industrial production, housing automation, and environmental monitoring. The creation of complex network architectures consisting of interconnected wireless devices that make up deice-to-device (D2D) or more generally, M2M communication networks is a key feature of 5G networks. Some IoT-generating appliances, sensors, or portable devices. Without causing congestion problems, the traffic created by various M2M and IoT applications must be properly allocated to the access point. Not all IoT devices [1] can be linked to a grid, so energy harvesting plays a key role in achieving the energy-neutral or permanent operation of a small battery wireless system. Energy harvesting and on-demand energy replenishment of depleted batteries [2] are two main technologies that will allow the IoTs to work sustainably
