(BCZT) nanowires are fabricated through electrospinning.The nanogenerators based on these nanowires are also fabricated.The effect of directional aligned nanowires on output performance of nanogenerators is studied.X-ray powder diffraction and Raman spectrums show that these nanowires have good
tetragonal perovskite structures.Scanning electron microscope(SEM) images show that by utilizing parallel electrode collector
most of nanowires are oriented aligned. Test results of piezoelectric properties of nanogenerators show that average output current is 89.69 n A nano generators with directional aligned nanowires with random aligned nanowires
average output current is 52.36 n A.The current output characteristics of nano generators with directional aligned nanowires is increases by 71. 3 % compared with random aligned nanowires.Self-powered wearable flexion sensors made of these nanogenerators exhibit an excellent response
and can distinguish well the bending movements of different parts of the body without external power supply.
