Metamaterials Research

The team members research on metamaterials currently focuses on condition monitoring in ways of highly efficient sensing, additive manufacturing on vibration attenuation, piezoelectric materials for high performance energy harvesting.

Fig.1 shows 2 types of 3D-printed metamaterials, compare to conventional metamaterials, the 3D-printed ones are much easier fabricable through 3D-printing due to only one single material is needed.

Fig. 2 shows several shape types of piezoelectric patches, in order to achieve efficient energy harvesting results, the idea of metamaterials is applied to piezoelectric energy harvesting in terms of optimizing the arrangements, reshaping the geometry of the patches. As a result, the waste energy omitted from the rotating machine can be efficiently harvested and applied on self-powering sensors.
