TL;DR: In this paper, a hybrid piezoelectric wind energy scavenger with different cross-sectioned bluff bodies is presented to enhance the energy scavenging performance by coupling both the vortex-induced vibrations (VIV) and galloping phenomena.

TL;DR: In this paper, the authors investigated a technique for broadband vibration suppression using a graded metamaterial beam, where a series of local resonators with the same mass but different natural frequencies are attached to the beam, and a design strategy was proposed, and used to tune the frequency spacing to get a wide attenuation region.

TL;DR: In this paper, the authors explored the use of metasurface in designing an aerodynamic system for potential vortex-induced vibration suppression or energy harvesting, and found that the presence of meta-surface patterns has a significant influence on the aerodynamic characteristics of the bluff body.

TL;DR: In this article, the authors presented an analytical study of a multifunctional system based on the concept of acoustic-elastic metamaterial (AEMM) that exhibits a stop band gap for wave transmission.

TL;DR: In this paper, a two-degree-of-freedom (DOF) piezoelectric energy harvester (PEH) with stoppers that introduce nonlinear dynamic interaction between the two DOFs was proposed.
