This research details a method for mathematically simulating and assessing thermal vibration energy harvesting in laminated bimorph nanoplates fluid contact. The model uses the piezoelectric characteristics of outer layers functionally graded (FG) core material to transform stresses into electrical efficiently. Nanostructures' size effects nonclassical behavior are captured by nonlocal strain gradient theory (NSGT). Combining Navier–Stokes equations with electromechanical obtained from Hamilton's principle, first-order shear deformation (FSDT), Gauss's law yields an advanced multi-physics model. FG exhibits variations power principle is composed both ceramic metal components. Analytical solutions frequency response functions that relate output external circuit load resistance solving coupled electromechanical-fluid equations. A thorough investigation conducted analyze how different elements impact performance using parametric studies. These factors include configuration harvester (either parallel or series connections), effects, temperature gradients, depth, load, geometric dimensions, properties layers, core.

In this article the bending behavior of sandwich plates with a Functionally Graded (FG) core Boltzmann-type viscoelastic integrated piezoelectric layers at top and bottom surfaces, is reported under electrothermomechanical loading within framework three-dimensional elasticity theory. For various boundary conditions, differential quadrature method (DQM) used to obtain semi-analytical solution along in-plane coordinate axes. The present formulation validated by comparing numerical results on bending, stress those published in literature. A complete parametric study performed reveal effect different parameters such as length thickness ratio, temperature gradient, mechanical loading, piezo-to-core relaxation time constant, applied voltage rectangular plates. show that an increase leads decrease deflection plate; Also due voltage, curve along-the-thickness nonlinear for FG core; but it was linear both layers.
