N2 - This paper proposes an electrostatic-piezoelectric hybrid vibrational power generator with different frequency broadening schemes. Both the nonlinear frequency broadening mechanisms and the synergized effect of the electrostatic-piezoelectric hybrid structures are investigated. On the one hand, we adopt the curved fixture structure, which has a 25% increase in bandwidth compared with the ordinary stopper structure. On the other hand, by integrating the electrostatic structure, the half-power bandwidth of the piezoelectric cantilever beam is 16Hz to 20Hz, and the peak power is 3.6mW, the half-power bandwidth of the electrostatic structure is 14.5Hz to 19.5Hz, and the peak power is 2.2mW. This means that under the same space utilization, the performance is improved by 60%. In this paper, the hybrid generator's structure and performance are optimized, and finally the response bandwidth and performance are improved. In general, the device designed in this paper has advantages such as larger bandwidth and better performance.
