In article number 2000058, Elda Hegmann, Torsten Hegmann, and co‐workers report on a zero‐power, optical, liquid crystal‐based sensor platform for various toxic gases and vapors. Two modalities are described, a ppm‐level time × dose and an acute exposure level image/text sensor, both for the use by firefighters, first responders, and personnel in chemical manufacturing as well as water purification plants.
