Intelligent facemask based on triboelectric nanogenerator for respiratory monitoring

Abstract

The fast-spreading of novel coronavirus disease (COVID-19) has been sweeping arount the globe and brought heavy casualties and economic losses, which creats 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.

A Mode of Intelligent Equipment Monitoring Optimization Based on Dynamic Programming Algorithm

“…At the same time, the collected monitoring data are massive (cloud monitoring data, a large number of applications of intelligent devices) and complex (there are a large number of unstructured monitoring data), which greatly reduces the accuracy of intelligent equipment monitoring in sports and cannot accurately reflect the intelligence of intelligent equipment devices. Because the mass and complexity are the inevitable trend of the development of intelligent equipment monitoring, a large amount of sports data of college students should be collected [ 9 ].…”
