The facemask contains at least one layer impregnated with a first chemical. When the facemask covers the respective user's mouth and nose, airborne particles of the first chemical are released from the at least one layer through the user's breathing. A sensor is configured to measure airborne concentration of the first chemical. A processing circuitry is configured to receive outputs of the sensor, to calculate a change in airborne concentration of the first chemical, and to issue a notification when the airborne concentration of the first chemical increases at above a predetermined rate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Automatic particle or scent tracing to check social distancing in public places","description":"A kit includes at least one facemask configured to cover a respective user's mouth and nose.
