“…Shayestenia and Ghadiri 47 anticipated flexoelectric effects on the nonlinear dynamic instability of FG sandwich piezoelectric micro/nanobeams using nonlocal strain gradient elasticity theory and von‐Karman hypothesis. Furthermore, Alam and Mishra 48 utilized the nonlocal strain gradient‐based on boundary layer concept to solve the nonlinear post‐buckling of thermo‐electro‐mechanical FG piezoelectric cylindrical nanoshell. Xie et al 49 and Fattahi et al 50 predicted the size‐dependent nonlinear secondary resonance of hard excited FG porous beams at microscale and nanoscale.…”

The applications of nanoelectromechanical systems integrating simultaneously the mechanical and electrical functionalities at nanoscale have been gotten wider in the last decade. The main objective of this exploration is to analyze the small scale‐dependent nonlinear dynamical feedback of multilayer energy nanoharvesters containing a graded porous passive core coated by piezoelectric facesheets under a sinusoidal impulsive external actuation. For this purpose, the technique of meshless collocation is constructed at the same time the nonlocal stress and strain gradient tensors without any necessary background meshes and integration procedure. It is found that by taking the nonlocal stress tensor into account, the average of extremum points of maximum lateral deflection increases from to , and from to for simply supported and clamped multilayer nanoharvesters, respectively. On the contrary, through considering the strain gradient tensor, the average of extremum values of the maximum lateral deflection reduces from to for the simply supported nanoharvester, and from to for the clamped one.Highlights Development a third‐order shear flexible nonlocal strain gradient (NSG)‐based plate‐type nanoharvester model Incorporating the role of nonlocal stress and strain gradient tensors in nonlinear dynamics of nanoharvesters Time‐histories of achieved voltage of sinusoidal impulsive loaded plate‐type nanoharvesters Influence of porosity on the NSG‐based nonlinear dynamic performance.
