Magnetically Driven Powerless Lighting Device with Kirigami Structured Magneto–Mechanoluminescence Composite (Adv. Sci. 17/2023)

Magnetically Driven Powerless Lighting Devices In article number 2207722, Michael Abraham Listyawan, Hyun‐Cheol Song, Jungho Ryu, and colleagues introduce novel concept of magnetically driven powerless lighting device by combining mechanoluminescence material and magneto–mechano‐vibration of cantilever structure. Such device has the potential to be a sustainable and efficient alternative lighting source as it can be driven by stray magnetic fields. The design, optimization, and testing in practical environments are summarized and presented. [Image: see text]
