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.
