Piezoelectric nanogenerators have attracted intensive interest in harvesting the stray mechanical energy environment to power miniaturized electronics and sensors. However, their efficient integration into systems compatibility with existing technologies for practical applications remains challenging. Here, we report first time systematic, data-driven learning of process-property-performance re...

in this paper, a numerical solution procedure is presented for the forced vibration of a piezoelectric nanowire under thermo-electro-mechanical loads based on the nonlocal elasticity theory within the framework of timoshenko beam theory. using hamilton’s principle, the nonlocal governing differential equations are derived. the governing equations and the related boundary conditions are discreti...

Large piezoelectric effect in nonlinearly graded lead-free ferroelectric thin films In article number 2100370, using extended phase field simulations, Le Van Lich and co-workers demonstrate that a large can be obtained film. The enhancement of property originates from the gradient electrical polarization, which makes polarization more susceptible to external excitation.

This contribution is aimed at presenting a computational method for assessment and prediction of mechanical property changes in soft tissue, in order to diagnose certain pathologies. This diagnostic technology is based on two components: a custom designed piezoelectric transducer that transmits and receives torsion ultrasound, and a model-based inverse problem that simulates using finite elemen...

The process of acquiring the energy surrounding a system and converting it into usable electrical energy is termed power harvesting. In the last few years, there has been a surge of research in the area of power harvesting. This increase in research has been brought on by the modern advances in wireless technology and low-power electronics such as microelectromechanical systems. The advances ha...

In this paper, the piezoelectric coefficient d33 of AlN thin films for MEMS applications was studied by the piezoresponse force microscopy (PFM) measurement and finite element method (FEM) simulation. Both the sample without a top electrode and another with a top electrode were measured by PFM to characterize the piezoelectric property effectively. To obtain the numerical solution, an equivalen...
