Abstract

The paper suggests to use a cholesteric liquid crystal (LC) doped by Fe2O3 magnetite, as the material of the primary transducer of carbon monoxide optoelectronic sensor. The sensor operation is based on the registration of changes in the reflectance spectrum of a cholesteric liquid crystal under carbon monoxide. The registration of changes in the reflectance spectrum is in the visible range of spectrum. The structural, functional and electrical schematic schemes of an optoelectronic sensor carbon monoxide are developed.
