“…The system can be expressed by the following equations: In [115,116], the authors proposed an EMEH circuit with close loop boost converter switch control through PWM for feedforward and feedback control as shown in Figure 19. The working principle of this model when the output voltage of the rectifier is bigger than the forwarding voltage of the diode and boost converter is that the voltage directly connects to the storage unit (i.e., capacitor, battery, supercapacitor) [116,117]. However, the limitation of this model is complex in terms of its need for a mathematical model, and it is also time-consuming and not suitable for low power devices such as EH applications.…”

The demand for power is increasing due to the rapid growth of the population. Therefore, energy harvesting (EH) from ambient sources has become popular. The reduction of power consumption in modern wireless systems provides a basis for the replacement of batteries with the electromagnetic energy harvesting (EMEH) approach. This study presents a general review of the EMEH techniques for autonomous sensor (ATS) applications. Electromagnetic devices show great potential when used to power such ATS technologies or convert mechanical energy to electrical energy. As its power source, this stage harvests ambient energy and features a self-starting and self-powered process without the use of batteries. Therefore, it consumes low power and is highly stable for harvesting energy from the environment with low ambient energy sources. The review highlights EMEH circuits, low power EMEH devices, power electronic converters, and controllers utilized in numerous applications, and described their impacts on energy conservation, benefits, and limitation. This study ultimately aims to suggest a smart, low-voltage electronic circuit for a low-power sensor that harvests electromagnetic energy. This review also focuses on various issues and suggestions of future EMEH for low power autonomous sensors.

“…The DC voltage obtained at the load shown in figure 2 is fluctuating in nature and contains ripples. The efficiency of the EH module depends on the power made available to the module and the effective power obtained at the load [22][23]26]. This can be improved with the help of impedance matching between the sensor array and the rectifier circuit.…”

The technical advancements made in the modern wireless sensor networks has enabled the realisation of low power modules incorporating various sensors. These developments have pushed the researchers to look at harvesting energy from the ambient environment. The reduced dependence on battery, its recharging or replacement bodes well for the environment. The energy harvesting modules can directly power only a few devices and that too only if they have very low power requirement. The typical energy harvesting module utilises dc-dc converters or rectifier-multiplier modules to achieve appropriate levels of output voltage. This paper provides a review on various power electronic converters used in such energy harvesting applications.

“…Photovoltaic cell applications in the form of photovoltaic panels (PVPs) became widely available, common, and efficient [16]. They found applications for compact, autonomous, and sustainable IoT devices [17], such as solar-powered BLE beacons [18], sensors [19], and also devices supplying energy in various ways: indoor light energy [20], hybrid radio and light energy [21,22], or hybrid thermal and light energy [23].…”

This paper presents the design and performance of an energy subsystem (ES) dedicated to hybrid energy harvesters (HEHs): wave energy converters (WECs) combined with photovoltaic panels (PVPs). The considered ES is intended for compact HEHs powering autonomous end-node devices in distributed IoT networks. The designed ES was tested experimentally and evaluated in relation to the mobile and wireless distributed communication use case. The numerical evaluation was based on the balance of the harvested energy versus the energy consumed in the considered use case. The evaluation results proved that the ES ensured energy surplus over the considered IoT node consumption. It confirmed the proposed solution as convenient to the compact HEHs applied for sustainable IoT devices to power them with renewable energy harvested from light and sea waves. It was found that the proposed ES can provide the energy autonomy of the IoT end node and increase its reliability through a hybrid energy-harvesting approach.
