Abstract:  In this talk, I will summarize the work being done by my research group. Broadly speaking, our work exists at the intersection of three areas – multi-functional materials, non-invasive imaging, and inverse methods. More specifically, we focus on nanofiller-enabled electrical properties in polymeric composites and how these properties can be utilized for intrinsic self-sensing and/or active property modulation via thermo-mechanical loading. The intersection of these areas has potential for application to diverse areas such as structural health monitoring (SHM) and nondestructive evaluation (NDE), novel sensing technology including additively manufactured (AM) sensors, bio-medical implants and technology, and next-generation materials with in-operation property reconfigurability.

In the first part of this talk, I will discuss the material systems with which we are working and our efforts to model their multiphysical properties across length scales. Next, I will discuss how we combine these multi-functional materials with electrical property imaging modalities for spatially distributed sensing. And lastly, I will summarize our work in inverse methods – the process of inverting stimulus-property relations in these materials in order to ascertain properties of interest (e.g. strains, stresses, damages, etc.) from electrical observations. Applications such as structural engineering, artificial skins, and medicine will be integrated throughout the talk.
