Application of smart bracelet based on 5G and body area network technology in monitoring key populations in the ward

Abstract Background: Using 5th Generation Mobile Communication (5G) and cloud Technology to design a smart bracelet for key populations during the epidemic, improve the efficiency of epidemic prevention and control, and limit epidemic transmission. Methods: A thermosensitive metal temperature sensor and positioning chip were used to develop a smart bracelet. The smart bracelet monitored the temperature changes and real-time positioning of 40 patients at different time points. To validate the efficacy of smart bracelets in monitoring key populations, a comprehensive assessment of their consistency and accuracy was performed using fixed-point data collected by high-precision mercury thermometers and cameras. Results: The body area network (BAN)-based smart bracelet's temperature monitoring during the COVID-19 epidemic was compared to that of a mercury thermometer at different time points of the key population, with ICC=0.883, showing a high consistency and accuracy. Analysis of the real-time positioning data obtained from smart bracelets and camera monitoring, yielded highly accurate outcomes, with a Kappa value of 0.494, a sensitivity of 46.4%, a specificity of 98.7%, and an accuracy of 0.968. Conclusion: 5G、BAN and other technology-based smart bracelets are feasible for temperature and displacement monitoring of key populations, can replace the duties of medical personnel in certain wards, reduce contact, and have the role of reducing hospital infection.
