The fast-spreading of novel coronavirus disease (COVID-19) has been sweeping around the globe and brought heavy casualties and economic losses, which creates dire needs for technological solutions into medical preventive actions. In this work, triboelectric nanogenerator for respiratory sensing (RS-TENG) has been designed and integrated with facemask, which endows the latter with respiratory monitoring function. The output of RS-TENG for respiratory flow can reach up to about 8 V and 0.8 μA respectively although it varies with different respiratory status, which proves the high sensitivity of RS-TENG for respiratory monitoring. An apnea alarm system can be constructed by combining the smart facemask with circuit modules so that timely alarm can be transmitted after people stop breathing. Furthermore, RS-TENG can be used to control household appliances, which brings convenience to the life of the disabled people. Considering its incomparable advantages such as small volume, easy fabrication, simple installation and economical applicability, such design is helpful for developing multifunctional health monitoring gadgets during the COVID-19 pandemic.
新型冠状病毒病（COVID-19）的快速传播席卷全球，造成了重大人员伤亡和经济损失，这迫切需要将技术解决方案应用于医疗预防行动。在这项工作中，设计了用于呼吸传感的摩擦纳米发电机（RS-TENG）并将其与口罩集成，使口罩具有呼吸监测功能。尽管RS-TENG对呼吸流量的输出会因不同呼吸状态而有所变化，但分别可达约8 V和0.8 μA，这证明了RS-TENG对呼吸监测具有高灵敏度。通过将智能口罩与电路模块相结合，可以构建一个呼吸暂停报警系统，以便在人们停止呼吸后及时发出警报。此外，RS-TENG可用于控制家用电器，为残疾人的生活带来便利。考虑到其体积小、易于制造、安装简单和经济适用性等无与伦比的优势，这种设计有助于在COVID-19大流行期间开发多功能健康监测设备。
