A team of students from Arizona State University have won the top XPrize $550,000 award for face masks, defeating more than 400 other entrants.
The ASU team, dubbed Luminosity Lab, came up with a mask design that includes a bifurcated filtration chamber that directs hot expelled breath away from the wearer’s face and out of the filter chamber rather than out the top of the mask as in many ordinary face masks.
Besides being more comfortable for the wearer, this technique ensures glasses don’t fog. The mask also lifts up easily for eating and drinking and includes what’s called a voice visualizer box. LEDs on the box light up when the wearer speaks, telling others in a group who’s speaking.
