A kind of lightweight metal‐based magnetostrictive FeCo/AlSi composite with twisted FeCo wires was fabricated by Fumio Narita and co‐workers, see article number 2000281 . The twisted design for the FeCo wires, combined with structure–thermal treatment finite element analysis, well demonstrates its merits to obtain a greater energy‐conversion performance. This work not only provides insights into the mechanism responsible for the mechanical–magnetic energy conversion but also offers a particular design concept for further improving the magnetostrictive properties or energy‐harvesting performance.
