The World Economic Forum is promoting a ‘smart mask’ that tracks your breathing and alerts you via an app if you wear it improperly or forget to wear it at all. Yes, really. A video clip posted to the WEF’s official Twitter account this morning hypes the “the mask of the future,” designed by Chinese firm CirQ Technologies. The smart mask tells you when to wash it, whether you’re wearing it properly, and alerts you via a sensor linked to a cellphone app when you’ve left it at home. The environmental benefits of the mask are also touted as it would cut down on the number of disposable face masks that end up in land fills.
