A flexible self‐powered piezoelectric nanogenerator (FSPN) of high power density was constructed using a poly (vinylidene fluoride) (PVDF) polymer matrix based on solution crystallization. Since the solubility parameter of the N‐methylpyrrolidone (NMP) was closed to that of the PVDF, the FSPNs fabricated by PVDF and NMP showed a high concentrations of β ‐phase and a high power density of 6.6 W/m 3 together with excellent mechanical properties and transparent. In addition, the FSPN retained its excellent performance even after 2000 cycles of cantilever vibration, which hold a great potential for harvesting mechanical energy for self‐powered systems and provide a simpler solution for energy collection and utilization in our actual lives.
