Abstract: Abstract. The acoustic black hole (ABH) structure creates an effective isolation zone between the vibration source and the sensitive area by employing a gradient material or an elastic structure. This approach significantly ...

Abstract: Abstract. This article systematically investigates the isolation performance of a double-beam system interconnected by a nonlinear X-shaped connector. Based on Hamilton's principle and geometric analysis, a dynamic model ...

Abstract: Abstract. This study introduces a novel piezoelectric energy harvester based on a diatomic sandwich beam structure, offering a promising solution for wireless sensors and IoT nodes to operate without chemical batteries. ...
