Single BaTiO3 nanowires-polymer fiber based nanogenerator

A single fiber-based nanogenerators present a good performance as wearable device for harvesting the energy of human movement. The spinning process makes the BaTiO3 nanowires aligned in the PVC matrix. The superior performance of the single fiber-based nanogenerator (SFBNG) may be attributed to both the high piezoelectric constant and the mechanical property. A maximum output voltage of 0.9V and output current of 10.5nA were obtained from the SFBNG when it bending by the finger movement. The enhanced performance, the flexibility and ultrahigh tensile strength of the composite fiber make it a promising materials for energy harvesting as wearable generators.186
