dc.description.abstract | Stretchable mechanical energy harvesters are in high demand as sustainable power sources and self-powered systems for wearable electronics and biomedical devices. In this study, a stretchable flexoelectric-piezoelectric nanogenerator (FPENG) composed of a zinc-aluminum layered double hydroxide nanosheets-ZnO nanorods (ZnAl:LDH NSs-ZnO NRs) heterostructure is developed. The coupling of the flexoelectric effect of ZnAl:LDH NSs and the piezoelectric effect of ZnO NRs enhances the output performance of the FPENG. The FPENG generates an open-circuit voltage (V oc) of 41.5 V, a short-circuit current density (J sc) of 4.57 mu A/cm2, and a maximum power density of 68.2 mu W/cm2 with good mechanical durability, while the device under stretching at 60% strain generates a V oc of 1.85 V and J sc of 0.09 mu A/cm2. The energy generated from the FPENG is stored in a Li-ion battery, demonstrating a self-charging power unit. These findings present a simple method to develop FPENGs with enhanced performance by coupling flexoelectric and piezoelectric effects for wearable devices. | - |
