Brief Abstract:
Wearing a mask can increase facial temperature and cause thermal discomfort, which not only adversely affects mask mandate compliance, but also prompts poor mask fit and compromises mask protection. We quantified the microclimate dynamics and facial thermoregulation under facemasks with varying misfits using computational modeling, revealing significant temperature changes at different facial points. Additionally, our study elucidated leakage flows' impact on mask protection efficiency, highlighting even small gaps' substantial leakage potential. Leveraging sensor techniques, we accurately quantified leakage flows, providing insights into improving mask design and efficacy. Furthermore, we explored the potential of Schlieren imaging and neural network analysis in speech recognition, demonstrating promising avenues for automatic speech recognition and therapy through articulation flow analysis. These findings underscore the multifaceted implications of mask usage and the potential of advanced technologies in enhancing respiratory health and speech therapy.
