Sensing of markers for airborne particulate pollution by wearable colorimetry

摘要

A wearable pollutant indicator, methods of making and using same. The indicator includes a polymeric film substrate having a first side and a second side, an adhesive disposed on the first side of the substrate, and a readily understood user interface disposed on the second side of the substrate, wherein the user interface comprises a qualitative indicator of the accumulated exposure to incident airborne particulate pollution as sensed through the reaction of the transition metal oxides therein.
