MIT的cMaSK技术将评估口罩对个人用户的适合程度_我的网站

A |     (ECNS) -- Singapore Prime Minister Lawrence Wong, speaking in Chinese, underscored the importance of bilingual education and urged families to create environments where children can enjoy the language.     Wong said more than 1,000 students have benefited from expanded advanced Chinese courses this year, with about one quarter of Secondary 1 students enrolled.        He cited examples of Straits Times reporter Alyssa Woo improving language fluency by immersing herself in Chinese entertainment, from TV dramas such as Pursuit of Jade to songs by Pop icon Jay Chou.    “Watching dramas and listening to songs can really help with learning Chinese,” Wong said, encouraging people to find enjoyable ways to practice the language.    He added that dialects remain a cultural bond, recalling watching the Teochew version of the film Dear You.    Singapore and China’s national libraries will co-host an exhibition on the Four Great Classical Novels later this year.    Wong stressed that Chinese has become a common language among Singapore’s Chinese community and should continue to serve as a bridge to Chinese-speaking communities worldwide.    He stressed that Singapore should continue promoting Chinese as an important part of its multicultural identity and a bridge to Chinese-speaking communities around the world.    (By Helen Mo & intern Liu Shuangjing)                    。    该工具被称为cMaSK（可适配的多模态传感器口罩），旨在成为通常只在医院等设施中出现的口罩贴合度测试机器的一个更便宜、更容易获得的替代品。后者通过比较有关口罩内外的空气颗粒浓度来评估口罩是否合适。cMaSK采取了一种不同的方法。

B | 它基本上是一个灵活的矩形框架，由一种称为聚酰亚胺的生物相容性聚合物制成，沿着口罩的内侧边缘临时粘附。该聚合物中嵌入了17个电容式传感器、两个温度/湿度传感器和一个气压传感器。该设备还集成了一个加速器和一个蓝牙模块。

C | 当用户最初将口罩戴在脸上时，电容式传感器检测框架(以及口罩)的哪些部分与皮肤接触，哪些部分没有接触--为了达到理想的密封效果，它们应该几乎都接触到皮肤。同时，温度、湿度和压力传感器检测用户的活动，如说话和咳嗽--加速计检测身体运动，如走路和跑步。

D | 所有的信息都通过蓝牙传输到一个在移动设备上运行的应用程序，该程序反过来访问一个服务器，利用机器学习算法来分析数据。然后应用程序告诉用户口罩的适合程度，以及不同的活动和运动对适合程度的影响。当cMaSK在五名男性和五名女性身上进行测试时，研究人员发现它的贴合数据与麻省理工学院环境、健康和安全办公室的训练有素的人员手动收集的数据密切对应。应该注意的是，总体而言，测试的口罩被发现更适合男性。现在人们希望这项技术不仅可以用来帮助人们选择适合他们的可重复使用的口罩，而且还可以指导制造商设计更适合的口罩。这项研究由Canan Dagdeviren, Siqi Zheng, Tolga Durak和Jin-Hoon Kim领导。关于这项研究的论文最近发表在《自然-电子学》杂志上。
