The existing rectangular piezoelectric cantilever beam has the shortcomings of high intrinsic frequency and low output performance. In this paper，a piezoelectric energy harvester based on the enhanced negative Poisson’s ratio structure is designed by combining a negative Poisson’s ratio structure and X-shaped ribs in an elastic substrate. The dynamics model of the energy harvester is established by using the finite element method for the piezoelectric coupling analysis and parametric analysis. The prototypes are fabricated to verify the design. The results show that the energy harvester based on enhanced negative Poisson’s ratio structure has a low first-order resonant frequency，high output voltage and power，and the addition of X-rib increases the stiffness and nonlinearity of the structure. Compared with the conventional negative Poisson’s ratio structure，the introduction of X-rib not only improves the fatigue performance of the structure，but also broadens the bandwidth by 67.87%. The energy harvester based on enhanced negative Poisson’s ratio structure is important for solving the power supply problem of wireless sensors and portable electronic mobile devices in the future.
