“… 24 Thus, direct measurement of respiratory biomarkers, for example, respiratory rate, cough frequency, cough intensity, respiratory effort, and on‐site viral‐specific VOCs, 25 represent a potential game‐changer in the diagnosis, monitoring, and management of COVID‐19. 26 To date, bioelectronics, the convergence of biological systems and electronic devices, have witnessed tremendous progress in wide applications, 27 , 28 , 29 , 30 , 31 , 32 , 33 such as biosensing, 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 electrical stimulations, 45 , 46 , 47 neuromodulation, 48 drug delivery, 49 , 50 , 51 energy harvesting, 52 , 53 , 54 energy storage, 55 , 56 , 57 thermoregulation, 58 display, 55 imaging, 59 and many others. Specifically, respiratory sensors propelled by advanced bioelectronic technology have been widely used for health assessment, disease diagnosis, and treatment tracking in daily life.…”
