Cognizant Composites

We are developing a set of techniques for embedding sensors, circuitry, and electronics into structural composites. As team of human computer interaction and civil engineering researchers, we leverage recent developments in both fields to create sensors and circuitry that are seamlessly incorporated into structural composites. We fabricate bend and compression sensors, along with circuitry, from textiles, which enables us to add electronic capabilities without impacting the composite’s structural integrity. We describe the construction of these “cognizant composites” and demonstrate their functionality. We also explore techniques for embedding standard electronic components, including microcontrollers, into structural composites. Finally, we discuss this work in the context of the emerging area of human-infrastructure interaction. Potential applications of this technology include buildings that can warn occupants if load-bearing components are experiencing unexpected strain, bridges that can document traffic patterns, and delicate structures, like satellites, that can detect and perhaps control their own shape.
