This paper presents a single-input multi-output converter with backup battery for energy harvesting system of the gas sensor. Energy harvesting techniques used to catch energy from ambient light through photovoltaic (PV) modules as the main power source and regulate two outputs - 3.3V and 15V for different loads by a dc-dc converter. The backup battery is connected to input and output side of this system as a source and a load, when the PV energy more than the power of load, surplus energy charged in the rechargeable battery, when the ambient energy small than power of load, converter will storage power from PV cells, then charge power from battery and feed energy to the load. Finally, a multi-output converter for energy harvesting system is implemented to verify the precision of control strategy, light input and heavy input condition proposed in this paper.

Simulation Results

To guarantee the uninterrupted operation of an IoT node, IoT nodes are installed with energy harvesting techniques to prolong their lifetime and recharge their batteries. Mostly energy harvesting systems collect energy from sunlight and wind. However, the energy harvested from the sunlight is non-continuous and energy harvested from the wind is insufficient for continuously powering an IoT node. Thus, to resolve this problem, authors proposed an energy harvesting system namely SWEH which harvests energy from solar light and wind. In this article, authors proposed a scheduling algorithm to balance the energy produced by SWEH and the energy consumption of an IoT node that results in the energy neutral system. Results from simulation analysis clearly manifest that the proposed SWEH system extracts more energy as compared to energy produced by a single solar panel or wind turbine. With the help of simulation results, authors also show that the proposed algorithm leaves the system in energy neutral state at the end of particular time frame.

Energy Harvesting System

The purpose of the reported research is to study the implementation of a sub-one gram, multisource energy harvester, for use on a Cyborg Micro Air Vehicle (CMAV). The CMAV would combine a biological flight platform with onboard communications, flight control, and power generation, providing a useful surveillance and reconnaissance vehicle. The biological platform chosen in this research is the Manduca sexta (Hawkmoth). A multisource energy harvester consisting of photovoltaic cells and a piezoceramic beam is discussed, enabling energy harvesting from vibration as well as ambient light. This paper discusses the results of those investigations and addresses the difficulties in creating the energy harvesting system.

The harvesting of ambient energy has become more important over the last years. This paper will investigate an analytical effort to predict the Duffing parameters for a magnetoelastic cantilever structure. The modeling is compared to a nonlinear harvester with point dipoles. The system consists of a harmonic excited cantilever structure with a magnetic tip mass. The beam is firmly clamped to the host structure. A second oppositely poled permanent magnet is located near the free end of the beam. The system is a bistable nonlinear oscillator with two equilibrium positions. Several studies show the better performance of the setup. The approach is not limited for energy harvesting techniques. The setup is suitable for broadband oscillations and also to tune the resonant frequency closer to the excitation frequency.

Energy harvesting from wasted or unused power has been a topic of discussion for a long time. We developed ‘damper devices’ for precision machinery and automobile engine mats in the 1980s. However, in the 1990s we realized that electric energy dissipation on its own was useless, and started to accumulate the converted electric energy into a rechargeable battery. Historically, this was the starting point of ‘piezoelectric energy harvesting devices’.
