據MSN新聞網站5月14日報道，哈佛大學和麻省理工學院的研究人員正在開發一種口罩，當口罩檢測到新冠病毒時就會亮起來。

在有效的藥物和更困難的疫苗出來之前，這個最有希望改變美國現狀，拯救經濟。有不同意見，歡迎探討！

Jim Collins, whose bioengineering lab at MIT began work on the sensors in 2014, said the technology could be rolled out on a wider scale if it proves successful.

He said: "As we open up our transit system, you could envision it being used in airports as we go through security, as we wait to get on a plane.

The team are said to be in the “very early stages” of the project but are hoping to begin trials within the next few weeks.

Collins said once the sensors detect a trace of coronavirus, they will give off a fluorescent signal within one to three hours – considerably less time than the 24 hours it currently takes to run tests for coronavirus.
