Towards Cyber-Physical Systems - A Multifunctional Materials Perspective

Rapid global urbanization has been drastically transforming the built environment and human life. To accommodate the increasing urban population, $78 trillion is expected to be invested on infrastructure over the next 10 years. Forming the backbone of the global economy, infrastructure systems are nonetheless vulnerable to multi-hazards (i.e., natural and man-made disasters) and aging (i.e., structural performance degradation). To enhance urban resilience and sustainability, cyber-physical systems (CPS) have been proposed to measure the performance of a physical system (e.g., infrastructure and human occupants) and interact with the physical world based on data-driven analyses conducted in the cyber system.

One of the most crucial components of the CPS is the sensing system that provides data streams for digitizing the physical world. However, the complex damage modes, drastically different materials, intricate geometries, and diverse operational environments make it challenging for conventional sensors to effectively quantify structural health and human performance. Multifunctional materials, on the other hand, can be designed to realize novel sensing mechanisms that could be better suited for extracting relevant damage features and tailored for specific engineering applications. Therefore, this work aims to tackle the grand challenge of obtaining high-quality, scalable, and multi-modal data streams on structural and human performance through computationally and experimentally designing multifunctional material-based sensing systems.

The overarching research goal is to advance cyber-physical systems (CPS) to enable the built environment to intelligently and sustainably interact with humans, and hence to improve human safety and quality of life. This presentation will outline how carbon nanotube- and graphene-based sensing skins are designed and implemented for both infrastructure and human monitoring.
