Sangmin Lee, Sung-Hwan Bae, Long Lin, Ya Yang, Chan Park, Sang-Woo Kim, Seung Nam Cha, Hyunjin Kim, Young Jun Park and Zhong Lin Wang Energy Harvesting Materials: Super-Flexible Nanogenerator for Energy Harvesting from Gentle Wind and as an Active Deformation Sensor (Adv. Funct. Mater. 19/2013) Advanced Functional Materials 23
To construct super-flexible and conformable nanogenerators, ZnO nanowires are grown on 18-μm-thick Al foil, which is used as both the electrode and the substrate. Coating the Al foil with poly(methyl methacrylate) before the growth of ZnO nanowires results in a high-throughput process due to complete insulation between the as-grown ZnO nanowires and the Al foil. As reported by Zhong Lin Wang and co-workers on page 2445, this super-flexible nanogenerator shows potential as an energy harvester from a waving flag and as a self-powered sensor for detecting skin movement.
