The project aims to generate a fundamental understanding of the underlying multiphysics of dual-functional locally resonating metastructures, where undesirable vibrations are suppressed while absorbed energy is converted into electricity. It will widen low-frequency vibration suppression gaps and maximise energy capture by formulating an integrated modelling framework to leverage complex dynamics of nonlinear local resonators coupled with vibration energy harvesting mechanisms and nonlinear electrical circuitry. This will promote the development of next-generation multifunctional metastructures. Knowledge produced should improve the durability of structural components and empower sustainable wireless monitoring with self-powered sensors.Read moreRead less

This project intends to improve our understanding of the influence of surface stress on bending in anisotropic crystalline plates. Micro/nanoelectro-mechanical systems as transducers, switches, logic gates, actuators and sensors are widely used in fields of biotechnology, medicine, automotive, civionics, avionics and defence. A key issue that affects the accuracy and reliability of these systems is how to correctly predict the size-dependent surface stress of the structural components in the systems. The project aims to quantify the relations between the change in surface stress and the bending of structures with micro/nanoscale thickness and arbitrary crystallographic symmetry. Expected project outcomes may lead to significant advancement in overcoming the current shortcomings in designing micro/nanoelectro-mechanical devices.Read moreRead less
