“…Both AS1 and AS2 were elliptical based and were found to be giving more power than conventional cantilever design. M Taylor et al [ 43 ] investigated a similar elliptical‐based design to increase piezoelectric energy harvesting. Further, it is important to note that the auxetic structure (i.e., re‐entrant, chiral, s‐shape, elliptical, missing rib, porous foam, crumpled sheet, entangled single wire, etc.)…”

“…[34] Hence, eliminating these drawbacks and getting an effective conversion of energy hybrid/combined energy harvester is required. Several methods have been used to enhance the piezoelectric energy harvesters, such as loading criteria, [35,36] functionally graded designs, [37][38][39][40][41][42][43][44] and structural designs of the harvester. [45][46][47][48][49] There has been a rise in the application of auxetic structures for enhancing piezoelectric energy harvesters in recent years.…”

This study proposes a separate and combined (pyroelectric + piezoelectric) energy harvesting system using a bimetallic beam. Hybrid energy harvesting is achieved by waste thermal energy using thermal expansion mismatch of the bimetallic beam. In this regard, four types of design are proposed, along with various heating/cooling cycles. Auxetic layers in a bimetallic beam are used to enhance the power. The best‐performing design and heating/cooling cycle are considered for further power increment. Two models are simulated based on low (model C3) and high heat consumption (model C5). The load resistance, frequency, bimetallic beam and pyroelectric/piezoelectric layer thickness are varied and maximum power is obtained at 175 MΩ (C3), 75 MΩ (C5), 0.02 Hz (C3 and C5) and 0.4 mm (C3 and C5) as 20 μW (C3) and 40 μW(C5), respectively. The piezoelectric, pyroelectric and combined power variation is the effect of stress and temperature fluctuations on H‐PEH layer. Additionally, five well‐known higher pyroelectric/piezoelectric coefficient materials are studied and found that La‐NBT‐BT‐Ta gives the maximum power of 0.811 and 1.99 mW for combined (pyroelectric + piezoelectric) effect in low (C3) and high (C5) heat consumption model, respectively. The stress generated in both models is analyzed to look at practical feasibility.

Herein, vibrational behavior of functionally graded (FG) smart piezoelectric sandwich plates with honeycomb core resting on viscoelastic foundation under the effect of 2D magnetic field is presented. By varying the magnetic-field magnitude and its direction, the vibrations can be controlled. The plate is composed of two FG piezoelectric layers bonded with honeycomb structure as a mid-layer. Magnetic Lorentz force will be deduced via Maxwell's relations. A new quasi-3D plate theory considering the shear and normal deformations is incorporated to evaluate the displacements. The governing equations of motion are introduced via Hamilton's principle. Galerkin technique is considered to solve the motion equations for different boundary conditions. Influences of the magnetic field, boundary conditions, electric voltage, and core thickness on the eigenfrequency of the FG sandwich piezoelectric plate are illustrated. It is found that considering the effect of the magnetic field on the smart devices increases their vibrations, which may lead to an increment in the energy harvested from them. Further, when the magnetic field is applied along the length of the rectangular plate, the vibrations are reduced and vice versa.

In present research exploration, the nonlinear dynamic stability characteristics of axially compressed nanocomposite plates at micro/nano-scale reinforced with randomly oriented carbon nanotubes (CNTs) are investigated within the both prebuckling and postbuckling regimes. To accomplish this examination, the nonlocal couple stress (NCS) continuum elasticity is incorporated to a quasi-3D plate theory which separates the plate deformation to the bending and shear parts considering simultaneously the transverse shear and normal displacements. In addition, a two-parameter homogenization scheme is utilized to obtain the effective characters of the randomly oriented CNT-reinforced nanocomposites. The NCS-based nonlinear differential equations of motion are discretized using the Kronecker tensor product together with the shifted Chebyshev-Gauss-Lobatto gridding pattern. Thereafter, the Galerkin technique together with the pseudo arc-length continuation method are employed to achieve the NCS-based frequency-load and nonlinear frequency ratio-deflection curves before and after of the bifurcation point. It is deduced that for a randomly oriented CNT-reinforced heterogeneous micro/nano-plate in which the most CNTs are located inside clusters, increasing the value of cluster volume fraction leads to increase a bit the significance of the softening and stiffing characters related to the nonlocal and couple stress tensors before the bifurcation phenomenon, but it causes to decrease them after the critical bifurcation point. Opposite patterns before and after the bifurcation phenomenon are predicted for the agglomeration in which the most CNTs are located outside clusters.
