_Designing Advanced Respiratory Protective Devices for Pandemics: Performance, Mechanism and Future Perspectives_ identifies emerging and critical issues that directly or indirectly influence the protective performance of Respiratory Protective Devices (RPDs), along with important future research directions. The severity of the COVID-19 pandemic emphasizes the vital role of respiratory protection provided by PPE (and RPD) in novel infectious respiratory disease control. A wealth of recent research on coronavirus mitigation measures is combined with prior information on infectious diseases, RPDs, and human physiological and psychological responses to make this a fundamental resource on recent advances, innovative perspectives on respiratory protection, and new applications. The effectiveness of such disease control measures rely greatly on the performance of the RPD, user compliance, and proper use. Only an interdisciplinary approach to this issue can lead to success. * Combines introductory material on the nature of infectious disease and mechanisms of respiratory protection with cutting-edge research * Examines the different material properties that lead to successful RPDs, including breathability, comfort, and recyclability * Explains different methods for RPD test, evaluation, and approval from regulatory agencies worldwide
