Lightweight, Low-Power, Inexpensive Ozone Dosimeters

Lightweight, low-power-consumption, inexpensive ozone sensors based on colorimetric chemical sensing would be developed, according to a proposal. Colorimetric chemical sensing is an established technique, but it has not been applied previously to sensing of ozone. The proposed ozone sensors could be incorporated into radiosondes for measuring tropospheric and stratospheric ozone concentrations; they could also be used to monitor ozone in a variety of indoor and outdoor environments near such ozone sources as electric-arc welding equipment, high-voltage laboratory instruments, photocopiers, laser printers, and electrostatic air cleaners.
