Hygroelectric Generators: Rollable, Stretchable, and Reconfigurable Graphene Hygroelectric Generators (Adv. Mater. 2/2019)

Rollable, stretchable and three‐dimensional space‐deformable graphene‐based hygroelectric generators (GHEGs) are developed by a laser processing strategy by Huhu Cheng, Liangti Qu, and co‐workers in article number 1805705 . These GHEGs exhibit excellent electricity‐generation ability under their fascinating interaction with water molecules, and are promising as a power supply for applications in complicated and deformable conditions.
