Flexible Hybrid Piezoelectric‐Electrostatic Device for Energy Harvesting and Sensing Applications

Abstract Converting mechanical energy from either the ambient environment or human body motions to useful electrical will revolutionize power solutions for flexible electronics. Here, a hybrid harvesting strategy is reported, which combines porous polymeric piezoelectric film with an electrostatic layer as integration converting into energy. The materials through engineered microstructures are developed enhance generation due higher compressibility and larger surface contact area. effect charged further contributes of charges. By directly coating stretchable carbon nanotubes onto elastomers, more intimate harvesters enables designs complex Such piezoelectric‐electrostatic device exhibits superior performance voltage output 1.95 V, improves 30% 100% compared alone device, respectively. Experiments also performed demonstrate implementation device's conversion small electronics recognition different motions. provides new solution toward future revolution
