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.

该项目旨在对双功能局部共振亚结构的基础多物理学产生基本的理解，在这种亚结构中，当吸收的能量转化为电能时，不希望的振动被抑制。它将扩大低频振动抑制差距，并通过制定一个综合建模框架来最大限度地利用非线性局部谐振器与振动能量收集机制和非线性电路耦合的复杂动力学来最大限度地捕获能量。这将促进下一代多功能元结构的发展。所产生的知识应提高结构部件的耐用性，并通过自供电传感器实现可持续的无线监测。
