Since its outbreak in 2019, COVID-19 becomes a pandemic, severely burdening the public healthcare systems and causing an economic burden. Thus, societies around the world are prioritizing a return to normal. However, fighting the recession could rekindle the pandemic owing to the lightning-fast transmission rate of SARS-CoV-2. Furthermore, many of those who are infected remain asymptomatic for several days, leading to the increased possibility of unintended transmission of the virus. Thus, developing rigorous and universal testing technologies to continuously detect COVID-19 for entire populations remains a critical challenge that needs to be overcome. Wearable respiratory sensors can monitor biomechanical signals such as the abnormities in respiratory rate and cough frequency caused by COVID-19, as well as biochemical signals such as viral biomarkers from exhaled breaths. The point-of-care system enabled by advanced respiratory sensors is expected to promote better control of the pandemic by providing an accessible, continuous, widespread, noninvasive, and reliable solution for COVID-19 diagnosis, monitoring, and management.
自2019年爆发以来，新冠病毒已成为大流行病，给公共医疗系统带来沉重负担并造成经济负担。因此，世界各国社会都将恢复正常作为优先事项。然而，由于新冠病毒传播速度极快，对抗经济衰退可能会使疫情死灰复燃。此外，许多感染者在数天内没有症状，导致病毒意外传播的可能性增加。因此，开发严格且通用的检测技术以持续检测全体人群中的新冠病毒仍然是一个需要克服的关键挑战。可穿戴呼吸传感器可以监测生物力学信号，如新冠病毒引起的呼吸频率和咳嗽频率异常，以及生化信号，如呼出气体中的病毒生物标志物。先进呼吸传感器支持的即时检测系统有望通过为新冠病毒的诊断、监测和管理提供一种可及、持续、广泛、无创且可靠的解决方案，促进对疫情的更好控制。
