Special Issue Information

Dear Colleagues,

Piezoelectric materials are smart materials that exhibit unique electromechanical coupling, which enables engineering designs to have more innovative features and functions. Piezoelectric nanomaterials have recently received growing interest with the miniaturization of electromechanical devices down to submicro- or nano-scales. These novel materials are particularly attractive for applications in energy harvesting, sensing, actuating, and among others. To achieve the optimal performance of these materials in their potential applications, it is essential to fully understand the underlying physics and mechanisms governing their size-dependent electromechanical coupling, which is believed to attribute to both surface effects and flexoelectricity.

This Special Issue will focus on recent advancements in the modeling and simulation of piezoelectric nanomaterials. We invite submissions of original research articles or comprehensive reviews on, but not limited to, continuum mechanics, finite element and atomistic modeling and simulation on the mechanical and physical properties of piezoelectric nanomaterials and their applications.

A hybrid nanowire (HNW) was constructed by coating a single-wall carbon nanotube (SWCNT) with piezoelectric zinc oxide (ZnO). The two components of the HNW interact with each other via the van der Waals (vdW) force. This paper aims to study the effect of the piezoelectricity in the ZnO layer and the inter-phase vdW interaction on the fundamental vibration of the HNWs. In doing this, a new model was developed where the two components of the HNWs were modeled as Euler beams coupled via the interphase vdW interaction. Based on the model, the dependence of the frequency on an applied electrical voltage was calculated for HNWs of different geometric sizes to reveal the voltage effect. The results were then compared with those calculated without considering the inter-phase vdW interaction. It was found that the interphase vdW interaction can substantially decrease the structural stiffness, leading to a greatly enhanced piezoelectric effect but a lower frequency for the vibration of the HNWs.

Piezoelectric nanomaterials (PNs) are attractive for applications including sensing, actuating, energy harvesting, among others in nano-electro-mechanical-systems (NEMS) because of their excellent electromechanical coupling, mechanical and physical properties. However, the properties of PNs do not coincide with their bulk counterparts and depend on the particular size. A large amount of efforts have been devoted to studying the size-dependent properties of PNs by using experimental characterization, atomistic simulation and continuum mechanics modeling with the consideration of the scale features of the nanomaterials. This paper reviews the recent progresses and achievements in the research on the continuum mechanics modeling of the size-dependent mechanical and physical properties of PNs. We start from the fundamentals of the modified continuum mechanics models for PNs, including the theories of surface piezoelectricity, flexoelectricity and non-local piezoelectricity, with the introduction of the modified piezoelectric beam and plate models particularly for nanostructured piezoelectric materials with certain configurations. Then, we give a review on the investigation of the size-dependent properties of PNs by using the modified continuum mechanics models, such as the electromechanical coupling, bending, vibration, buckling, wave propagation and dynamic characteristics. Finally, analytical modeling and analysis of nanoscale actuators and energy harvesters based on piezoelectric nanostructures are presented. Full article
