From: A smart mask for active defense against airborne pathogens
(a) Droplets expelled from mouth during various activities like exhalation, coughing, and sneezing create aerosol clouds that travel to different distances. (b) Expelled droplets containing suspended virus particles are small and easily turn into aerosols (left). The proposed ADAPT smart mask sprays mist on these particles (right), which loads them (i.e., increases their size and mass) and thus causes them to rapidly fall to the ground.
