摘要

Energy harvesting using piezoelectric nanomaterial provides an opportunity for advancement toward self-powered electronics. The fabrication complexity and limited power output of these nano/micro generators have hindered these advancements. This paper introduced a flexible and light weight nanogenerator package that was obtained by variety of additives (ZnO, CNT, LiCl, PANI) and try to have comparisons between them to choose appropriate one base on final application. Performances of these additives were evaluated using Fourier Transform Infrared, Scanning Electron Microscopy, Impedance analyzer, and traction-compression machine. The excitation method is based on low velocity impact test by falling down a ball on samples. Results show that for all additives there is a direct connection between beta phase formation and output voltage. CNT nanoparticles lead to have more beta Phase formation and higher output voltage (0.9 V) for electrospun web with 230 mu m thickness. The results imply promising applications, as an enhanced efficiency energy-scavenging interface, for various wearable self-powered electrical devices and systems.
