Via numerical analysis by using stochastic differential equations and colored-noise inputs, this study shows that a symmetric configuration of the curved-beam hinges in electret-based harvesters can produce higher (up to 8% more) power outputs than an asymmetric one. It also presents that the harvesters with curved-beam hinges can produce higher (up to 4.4 times) power outputs than those with straight hinges when the vibration magnitude is 0.05g.eninfo:eu-repo/semantics/closedAccessEnergy HarvesterMechanical VibrationNonlinear SpringCurved BeamElectretConference Object10.1109/DTIP58682.2023.102679532-s2.0-85175237128
