A Nonlinear Damped Metamaterial: Wideband Attenuation with Nonlinear Bandgap and Modal Dissipation
Bao Zhao, Henrik R. Thomsen, Xingbo Pu +6
In this paper, we incorporate the effect of nonlinear damping with the concept of locally resonant metamaterials to enable vibration attenuation beyond the conventional bandgap ran…
Time-sharing Orbit Jump and Energy Harvesting in Nonlinear Piezoelectric Energy Harvesters Using a Synchronous Switch Circuit
Bao Zhao, Jiahua Wang, Guobiao Hu +3
Nonlinearity has enabled energy harvesting to advance towards higher power output and broader bandwidth in monostable, bistable, and multistable systems. However, challenges in ope…
A Graded Metamaterial for Broadband and High-capability Piezoelectric Energy Harvesting
Bao Zhao, Henrik R. Thomsen, Jacopo M. De Ponti +5
This work studies a broadband graded metamaterial, which integrates the piezoelectric energy harvesting function targeting low-frequency structural vibrations, lying below 100 Hz.…
