Electromechanical analysis of functionally graded panels with surface-integrated piezo-patches for optimal energy harvesting

A new framework for optimizing energy harvesting from smart composites integrated with piezoelectric patches utilizing lamination parameters

“…illustrates the representation of the two piezo patches connected to a resistive load in the form of an equivalent circuit. It is important to mention that when nonlinear circuits are utilized in conjunction with the piezo-patches, an alternative approach known as the equivalent impedance method can be employed, as proposed by (Aghakhani et al, 2019;Motlagh et al, 2021). By applying Kirchhoff's current law, the circuit equation can be formulated:…”

“…Energy harvesting has been a primary focus of research by (Motlagh et al, 2021) highlighting the potential of piezoelectric materials in this design domain. The generated voltage difference can be effectively captured and subsequently utilized as a viable source of electrical energy (Howells, 2009).…”

“…A comprehensive understanding of the intricate interplay between these vibrational parameters and the resulting energy harvesting performance is crucial for devising effective optimization strategies (Motlagh et al, 2020). Piezoelectric materials, in the form of patches or layers, are predominantly employed in the field of structural engineering for their integration onto the surfaces of flexible beam or plate-like structures (Lahe Motlagh et al, 2023;Motlagh et al, 2021). In this research study focuses on the investigation of energy harvesting techniques through the integration of vibrating laminated composite plates with piezoelectric patches.…”
