Abstract Beams, plates, and shells, as the fundamental mechanical structures, are widely used in microelectromechanical systems (MEMS) nanoelectromechanical (NEMS) sensors, actuators, energy harvesters, among others. Deeply understand electromechanical coupling of these dielectric structures is crucial for designing, fabricating, optimizing practice devices systems. Herein we demonstrate flexoe...
Abstract Composite materials are widely used in aerospace industries due to their light weight, strength, and various other desired properties. However, they susceptible defects occurring during the manufacturing process or service. Typical include porosity, wrinkles, delamination. Nondestructive means of detection at any stage great importance ensure quality safety composite structures. A noni...
A high-performance flexible piezoelectric nanogenerator (PNG) is fabricated by a direct writing method, which acquires both patterned piezoelectric structure and aligned piezoelectric nanowires simultaneously. The voltage output of the as-prepared PNG is nearly 400% compared with that of the traditional spin-coated device due to the effective utilization of stress. This facile printing approach...
Abstract In this work, the state -space nonlocal strain gradient theory is used for vibration analysis of magneto thermo piezoelectric functionally graded material (FGM) nanobeam. An FGM constituent properties stated by using power law relations. The refined higher order beam and Hamilton’s principle have been to obtain motion equations. Besides, governing equations nanobeam are extracted devel...
