Filter face masks are Respiratory Protective Equipment designed to protect the wearer from various hazards, suit various health situations, and match the specific requirements of the wearer. Current traditional face masks have several limitations. In this paper, we present (ME)2, the Monitoring Equipment Mask Environment: an innovative reusable 3D-printed eco-sustainable mask with an interchangeable filter. (ME)2 is equipped with multiple vital sensors on board, connected to a system-on-a-chip micro-controller with computational capabilities, Bluetooth communication, and a rechargeable battery that allows continuous monitoring of the wearer's vital signs. It monitors body temperature, heart rate, and oxygen saturation in a non-invasive, strategically positioned way. (ME)2 is accompanied by a mobile application that provides users' health information. Furthermore, through Edge Computing Artificial Intelligence (Edge AI) modules, it is possible to detect an abnormal and early symptoms linked to possible pathologies, possibly linked to the respiratory or cardiovascular tract, and therefore perform predictive analysis, launch alerts, and recommendations. To validate the feasibility of embedded in-app Edge AI modules, we tested a machine learning model able to distinguish COVID-19 versus seasonal influenza using only vital signs. By generating new synthetic data, we confirm the highly reliable performances of such a model, with an accuracy of 94.80%.
过滤面罩是一种防护设备，旨在保护佩戴者免受各种危害，适合各种健康状况，并符合佩戴者的特定要求。目前传统的口罩有几个局限性。在本文中，我们提出了（ME）2，即监测设备口罩环境：一种创新的可重复使用的 3D 打印生态可持续口罩，带有可更换的过滤器。（ME）2 配备了多个 onboard 生命传感器，与具有计算能力的片上系统微控制器、蓝牙通信和可充电电池相连，允许连续监测佩戴者的生命体征。它以非侵入性的、策略性的方式监测体温、心率和血氧饱和度。（ME）2 配有一个移动应用程序，提供用户的健康信息。此外，通过边缘计算人工智能（Edge AI）模块，还可以检测到与可能的病理相关的异常和早期症状，可能与呼吸道或心血管系统有关，从而进行预测分析、发出警报和建议。为了验证嵌入式应用内边缘 AI 模块的可行性，我们测试了一个仅使用生命体征就能区分 COVID-19 和季节性流感的机器学习模型。通过生成新的合成数据，我们确认了该模型具有高度可靠的性能，准确率为 94.80%。
