Title: Health and Performance Assessment using Nanocomposites + Tomography
Abstract: Biological systems, like structures, are susceptible to different types of damage and are influenced by changes in operating conditions. Lessons learned from structural health monitoring (SHM) can potentially help improve sensing and diagnostic capabilities in the biomedical domain. This presentation outlines a new paradigm shift in human health and performance monitoring, where sensors are designed from a materials perspective stemming from a “bottom-up” design methodology. In doing so, one can engineer multifunctional nanocomposites that possess a diverse suite of engineering functionalities, such as sensing of specific external stimuli (e.g., strain and pH). A few examples will be highlighted. The first case examines multifunctional graphene-based thin films engineered with electrical properties that are sensitive to strain for monitoring human motion and activity. A scalable fabrication method based on micro-plotting is proposed so that they are amenable to mass production, and sensor prototypes are validated for wearable sensing applications. In addition, by coupling the films with tomographic algorithms, these “sensing skins” are able to sense and localize features over large spatial domains. The second set of examples illustrate how one can leverage a different modality of electrical excitation to interrogate systems and characterize surface and subsurface changes in the biological system. Furthermore, nanocomposites embedded in the body, such as on implants and prostheses, then serve as passive elements that accentuate changes occurring in the tissue or human body (e.g., due to infection). A noncontact tomography algorithm and interrogation system is shown to map electrical property changes within the material, thereby enabling noncontact, noninvasive, surface and subsurface sensing. Numerical modeling and experimental results are presented.
