Acoustics in Mechatronics

Noise and vibration can be detrimental to the performance and life of mechatronics systems, as well as to the comfort of people. For instance, the performance of modern semiconductor manufacturing equipment that requires nanometer accuracy can be easily deteriorated by small external disturbances induced by vibration or acoustic excitation. Additionally, noise from an MRI machine can easily reach a noise level comparable to aircraft noise, leading to an unpleasant experience for patients.

Our research aims to address tackle these challenges posed by noise and vibration through the development of innovative metamaterial solutions. Metamaterials are engineered structures designed to exhibit exceptional properties rarely found in nature. Acoustic and vibroacoustic metamaterials offer the capability to control, manipulate, and harness acoustic waves and vibrations in unprecedented ways. We concentrate on developing fundamental mechanisms and analysis methods that can be ultimately applied across various mechatronics sectors.
