The authors investigate the magnetic flux leakage for a class of magnetostrictive FeCo alloys with a notch undergoing compression and impact with respect to energy harvesting. The magnetic flux leakage plays a crucial role in the practical energy transition in terms of the features for energy harvesting. Therefore, the corresponding situations are systematically studied by combining finite element analysis (FEA) with practical experiments. The FeCo alloys are categorized into three groups with different three-dimensional notch shapes, and the depths of the notches are 0, 0.5, and 1 mm, respectively. The parameters in both the simulations and practical tests are completely consistent. The results of compression test carried out with a stepwiseincreasing stress from 0 to 100 MPa reveal that the variations of magnetic induced flux increase with the increasing depth of the notches. The following FEA herein provides a feasible interpretation that the stress concentration around the notch is largely responsible for the notch-induced enhancement. The findings of the impacting experiments simultaneously exhibit an analogous tendency that the output power is proportional to the depth of notch. Furthermore, the stress rate has no obvious effect on the output electricity. The maximum magnitude of the improvement for the output power increases by almost 400% comparing the specimens with notches of 0 and 1 mm. This study indicates a promising feasibility to achieve vibrationenergy harvesting from various irregular components.

The internet of things (IoT) manages a large infrastructure of web-enabled smart devices, small devices that use embedded systems, such as processors, sensors, and communication hardware to collect, send, and elaborate on data acquired from their environment. Thus, from a practical point of view, such devices are composed of power-efficient storage, scalable, and lightweight nodes needing power and batteries to operate. From the above reason, it appears clear that energy harvesting plays an important role in increasing the efficiency and lifetime of IoT devices. Moreover, from acquiring energy by the surrounding operational environment, energy harvesting is important to make the IoT device network more sustainable from the environmental point of view. Different state-of-the-art energy harvesters based on mechanical, aeroelastic, wind, solar, radiofrequency, and pyroelectric mechanisms are discussed in this review article. To reduce the power consumption of the batteries, a vital role is played by power management integrated circuits (PMICs), which help to enhance the system’s life span. Moreover, PMICs from different manufacturers that provide power management to IoT devices have been discussed in this paper. Furthermore, the energy harvesting networks can expose themselves to prominent security issues putting the secrecy of the system to risk. These possible attacks are also discussed in this review article.

Summary Energy harvesting technologies are growing rapidly in recent years because of limitation by energy storage and wired power supply. Vibration energy is abundant in the atmosphere and has the potential to be harvested by different mechanisms, mainly through piezoelectric and electromagnetic means. Various architectural structures were also designed for several operating conditions, namely, resonance frequency and range thereof, acceleration, and energy extraction from several motions. The advantages and disadvantages were elaborated on, and improvements on ideas from current research were discussed in this review.
