Metastructures are metamaterial induced concepts implanted in structural design. The exploration of metamaterials was heavily steered by the path-breaking investigation of electromagnetic metamaterials, which exhibited properties like, negative permittivity and permeability1. This paved the way for mechanical met...
Elastic wave propagation and bandgaps mechanism of two-dimensional windmill-like elastic metamaterials 2023, Applied Acoustics Citation Excerpt : At the same time, the grille structures can possess bandgap characteristics due to the periodicity, which not only meet the mechanical properties but also have...
Besides, compared with the original performance of Douglas fir wood, the 3D-printed wood-like overlapping microlattice metamaterial still exhibits moderate mechanical and excellent transport properties in the macroscale (Supplementary Note 7 and Supplementary Figs. 26–28). In summary, we report a ...
5.3. Stiffness, strength, and toughness optimization analysis of novel twin-like lattice To further improve the mechanical properties by increasing the number of twinning boundaries in a lattice, we arrayed the central unit of the improved structure. The structure obtained in this way was the novel...
After developing their working door latch, Ion and her team began creating other mechanical machines, such as a Jensen walker, pantograph, and pliers. “These types of machines are very simple to fabricate, compared to the conventional manufacturing process of, for example, a door-latch mechanism...

2024, International Journal of Mechanical Sciences Citation Excerpt : Homogeneous thin panels with the addition of spring-mass resonators have higher acoustic absorption properties compared to flat panels [69–75]. Scholars have also made corresponding studies on the combination of localized resonant artif...
(i.e. the mechanical, electrical and acoustic characteristics of the fluid as well as the volume of fluid) are selected in accordance with a variety of factors including, but not limited to the frequency (wavelength) of the acoustic signal with which it is desirable to interact, as well as...
In recent years, engineers have replaced the conventional infrared light source and detector with microelectromechanical systems (MEMS) technology, miniscule components that bridge between mechanical and electrical signals. In the new work, researchers integrate metamaterials onto a MEMS platform to further...
Boston University mechanical engineers have created synthetic, sound-silencing structures—acoustic metamaterials—that can block 94% of sounds. Reza Ghaffarivardavagh (ENG) (front center) holds two of the open, ringlike structures over his ears while Stephan Anderson (MED) (left), Xin Zhang (ENG...
