Rebirth of Liquid Crystals for Sensoric Applications: Environmental and Gas Sensors

Figure 1

Typical dependence of ethanol concentration in the container as a function of time (measured by tin oxide sensor). Area marked as “Isot” corresponds to isotropisation, area “Bubl” corresponds to bubbles formation, and area “Inter” corresponds to changes in interference pattern. Injection of ethanol occurred at ca. 20th s (this point is marked as “Start”).
