Lab Description
Just take a look around, and you’ll immediately find that your life is very closely related to the vibration, acoustic and waves. Conversations in your daily life, noise from outside the window, vibrations in cars and buses, medical or industrial ultrasonic technologies, etc. Vibration, acoustics and waves are everywhere in our daily life. In fact, vibration, acoustics and wave technologies have been considered as a core technique not only in reducing undesired noise in our daily life but also in suppressing vibrations for ultra-high precision mechanical machines and obtaining extremely high resolution in cutting-edge medical devices.WAV Lab is focusing on developing new vibration, acoustics and wave systems that can break-through the current technical limits and open a new way to future mechanical systems. Especially, we are focusing on the research topic of ‘Metamaterial’. Metamaterials are artificial materials consisting of the array of very small microstructure. Owing to the microstructure’s unique configuration, metamaterials can exhibit extraordinary properties that cannot be observed generally. Above all, metamaterials can provide negative density or stiffness, which have been considered to be impossible to be achieved. Below is a photo of elastic metamaterial which actually realized negative density and stiffness. Accordingly, metamaterials exhibit interesting dynamic phenomena that are largely different from general materials, and by utilizing their extraordinary characteristics, metamaterials can be used to design very interesting vibration, acoustics and wave systems.
