Researchers at Roorkee-based Central Building Research Institute (CBRI) have developed a battery-poweredsmart face maskfor labourers deployed at building construction sites.
The affordable smart face mask will give protection to workers suffering from asthma, lung infections or other pulmonary disease from dust, they said. The researchers said the smart face mask gives pure air for breathing to users as it has multi-layer filters such as electrostatic, HEPA and laser arrangements.
