The National Science Foundation Division of Chemical, Bioengineering, Environmental, and Transport Systems awarded Arizona State University a $907,484 Project Grant under the Engineering (47.041) federal grant program. The grant will fund research to systematically understand sweat evaporation fundamentals and their role in human thermoregulation. Specifically, the university will develop an integrated method using macro videography, mid-wave infrared thermography, and optical coherence tomography to simultaneously measure sweat evaporation rates and visualize microscale sweat dynamics at skin sites under varying thermal stimuli. Additionally, experiments and modeling will explore factor contributions to sweat evaporation using artificial sweating surfaces of increasing complexity. Insights gained from this research have the potential to impact medical diagnostic development, energy-efficient building design, and industrial product development. The grant period is from August 1, 2022 to July 31, 2025.
