A novel liquid crystal temperature sensor based on modal control principle

Abstract

The well-known electrically-controlled anisotropic properties of liquid crystals not only have been valued in displays applications, but also have led to the conception of innovative approaches for a wide and diversified field of applications, such as optical communications, imaging, metamaterials, microwaves, biomedical, etc. Also, the fact that liquid crystals parameters have a strong dependence with temperature, has allowed researchers to extend the design of liquid crystal devices into the field of sensors. The simultaneous effect of both dependences, on voltage and temperature, has been recently exploited in a novel frequency-temperature liquid crystal transducer [1]...
