“…To solve those problems, a series of polymer–matrix composite doped by Terfeno‐D were prepared. [ 8–11 ] The ductility of these composites indeed has an improvement in a way but at the expense of the dramatic decrease in magnetostrictive properties. In addition, the rare‐element‐dependent feature for Terfenol‐D is difficult to reduce the production cost for wide industrialization.…”

Lightweight metal matrix composites have attracted a great attention for their technological application in aerospace, automotive, or sporting goods, and the multifunctionality of these composites will further expand the range of applications. Herein, a kind of lightweight 1–3 magnetostrictive FeCo/AlSi composites is investigated to evaluate the effects of the specific structure design and reverse magnetic field on the energy conversion under compression. The microstructure of the FeCo/AlSi composite before compression was observed, and the results indicate that there is a large bonding interface, which has the benefits of strain/stress transfer. Compared with the FeCo/AlSi composite with straight FeCo wire, a design with twisted FeCo wire significantly enhances the output performance of the magnetostrictive FeCo/AlSi composite. Furthermore, comparison of the output voltage for the FeCo/AlSi composite in the N–S mode (forward magnetization) and N–N mode (reverse magnetization) reveals that the reverse magnetization can improve the efficiency of the energy conversion notably. In addition, the results of the output voltage in the theoretical calculation are virtually consistent with that in practical measurement.

“…On the basis of this limitation, it has become clear that EH cannot be considered as a feasible power source in high-power applications. However, as could be predicted, increasing the number of devices that can be powered from harvested energy would make it possible to relieve other energy sources [ 4 , 5 , 6 , 7 , 8 ]. Obtaining energy for devices from the environment has found possible applications in many different markets, and the number of possible applications will grow continuously [ 9 , 10 , 11 , 12 , 13 ].…”

This paper presents the results obtained using the rapid demagnetization method in the case of an NdFeB magnet and a new hybrid core. The developed core consists of three basic elements: an NdFeB magnet, Terfenol-D, and a specifically developed metallic alloy prepared by means of a suction casting method. The main goal of proposing a new type of core in the event of rapid demagnetization is to partially replace the permanent magnet with another material to reduce the rare-earth material while keeping the amount of generated electricity at a level that makes it possible to power low-power electrical devices. To “capture” the rapid change of magnetic flux, a small number of coils were made around the core. However, the very low voltage level at very high current required the use of specialized electronic transducers capable of delivering a voltage level appropriate for powering a microprocessor system. To overcome this problem, a circuit designed by the authors that enabled voltage processing from low impedance magnetic circuits was used. The obtained results demonstrated the usefulness of the system at resonant frequencies of up to 1 MHz.

Carbon fiber reinforced plastic (CFRP) is an excellent choice in the areas where weight reduction is important and multi-functionalization of CFRP, especially by adding sensor capabilities, is a promising approach to realize lightweight battery-free devices in structural health monitoring (SHM). In this study, we fabricated hybrid CFRP with Fe-Co fibers and evaluated the inverse magnetostrictive response characteristics. It was shown that the measured magnetic flux density of the CFRP fluctuates in response to cyclic bending load. It was also revealed that our Fe-Co fiber inserted CFRP has damage self-sensing ability. In addition, it seems that the optimization of design and more experimental and numerical investigation improves the capability of the hybrid CFRP with Fe-Co fiber as sensor composite materials.
