Low-dimensional (LD) materials, with atomically thin anisotropic structures, exhibit remarkable physical and chemical properties, prominently featuring piezoelectricity resulting from the absence of centrosymmetry. This characteristic has led to diverse applications, including sensors, actuators, micro- nanoelectromechanical systems. While piezoelectric effects are observed across zero-dimensional (0D), one-dimensional (1D), two-dimensional (2D) LD challenges such as effective charge separation crystal structure imperfections limit their full potential. Addressing these issues requires innovative solutions, integration materials polymers, ceramics, metals, other porous proving a key strategy significantly enhance properties. review comprehensively covers recent advances in synthesizing characterizing composites based on materials. The synergistic combination substances, especially demonstrates notable performance improvements, addressing inherent challenges. also explores future directions developing composite highlighting potential applications various technological domains.

Abstract Recent advancements in fabrication techniques, such as the development of powder metallurgy, have made it possible to tailor mechanical properties functionally gradient piezoelectric (FGP) micro/nanostructures. This class structures can be used improve performance many micro/nanoelectromechanical systems because their spatially varying and electrical properties. The importance FGP micro/nanoscale has been demonstrated by growing number published works on size-dependent characteristics, including static bending, buckling, vibration, energy harvesters wave propagation using scale-dependent continuum-based models. Reviewing recent developments field non-classical continuum mechanics, this paper examines analysis porous micro/ nanostructures. Five sophisticated theories piezoelectricity—modified couple stress, strain gradient, surface effect, well nonlocal theory, for example—are given special consideration light potential forecast unusual characteristics micro/nanostructures devices. In future, with multi-field couplings may studied or designed, article a helpful resource.
