  Abstract

In order to meet the growing demand for flexible wearable electronic products, flexible piezoelectric nanogenerators have received widespread attention as a sustainable power source in wireless mobile devices. This article reported Barium Titanate/Polyacrylonitrile (BaTiO3/PAN) composite nanofiber membranes prepared via electrospinning technology to successfully disperse high dielectric constant BaTiO3 with varied concentration in PAN solution. The increase of BaTiO3 particles helps to improve the output voltage of PAN nanofibers, and the output performance of BaTiO3/PAN flexible composite piezoelectric nanogenerator is the best with an output voltage of 1.6 V and current of 5.6 nA, respectively, when the mass fraction of BaTiO3 is 15%. Such BaTiO3/PAN composite nanofiber membrane also exhibits excellent flexibility, plus an outstanding stability of the synthesized BaTiO3/PAN composite nanofiber membrane piezoelectric nanogenerator after 2000 cycles of mechanical testing, which enables it to have an enormous potential in wireless sensing and wearable device applications. Therefore, this BaTiO3/PAN piezoelectric nanogenerator can detect the current signals of the human body in states, such as elbow bending, knee bending, running, and breathing, providing a reference for the development of high-performance and self-powered wearable bioelectronic products.
