Abstract

2019 Copyright All rights reserved. The brittleness of bulk ferroelectric ceramics perplexes the fabrication process for energy harvesters and reduces their durability. As one-dimensional nanostructures, ferroelectric nanofibers possess excellent performance such as decreased elastic coefficient and increased d33 with the decrease of the diameter (Ico et al., 2016; Bai et al., 2012) [1, 2], and can be easily deformed by tiny irregular mechanical vibration, therefore they are extremely useful in the fabrication of energy harvesters. We prepared KNNS-BNKZ nanofibers, BZT-BNT nanofibers, and PZT nanofibers with great ferroelectric performance, and fabricated energy harvesters based on these fibers then discussed the mechanism of energy harvesting, and realized energy collection and storage.
