The detection of exposure to chemical hazards can save lives. American scientists have developed a smart and simple chemidosimeter based on a chemiresistive sensor combined with a near-field communication tag, which can be read-out by a smartphone. This chemically actuated resonant device (CARD) is made of simple components, is disposable, ready-to-use, needs no batteries, and can be worn as a badge by people who are likely exposed to chemical hazards. It is described in the journal Angewandte Chemie.
