Metamaterial is a kind of artifical material that can exhibit exotic properties by engineering their microstructures. This project involves developing and validating a new metamaterial that can be used for effecient vibration suppression and energy harvesting concurrently. Thanks to its special design of microstructures (local resonators), the metamaterial can filter waves in multiple frequency ranges and thus suppress broadband vibrations. This special design also presents an energy localization effect so that the vibration energy can be channelled to one local resonator and easily harvested with a single transducer, instead of harvesting discrete energy from a number of local resonators in the conventional metamaterial. Finite element model will be developed and experiment will be carried out to validate this new metamaterial design concept.
