The mission of the Smart Materials and Intelligent Structures (SMIS) Laboratory is to design adaptive structural components/systems for next-generation urban infrastructure, which possess unprecedented properties and functionalities. Our research in the SMIS Lab is thus directed towards advancing multi-disciplinary knowledge at the crossroads between ultrasonics, dynamics/mechanics, chemistry, and bioengineering, with the particular goal of developing a new sensing material that can seamlessly interact with structures and environments. At the intersections of these fields, we develop a unique set of ultrasonic tools capable of not only quantifying the current state of damage evolution in solid materials, but also stimulating molecules, and biological cells in soft materials.
