During the implementation of the project, modern experimental methods will be applied to ensure that the relevant physical mechanisms of the processes are clarified and in the conditions of the required cleanliness of the investigated objects. In theoretical studies and in computer calculations, methods have been applied that guarantee sufficient accuracy and reliability of results. Liotropic chromium liquid crystals combine a very high packing density with the ability to form ordered structures transmitted from aqueous solution to solid films. It was shown that the electric currents along the LCLC aggregates in the solid films are sensitive to the distance between the molecules in the aggregates and this distance depends on the humidity of the medium. Measurement of the electric current through the LCLC film printed on the substrate with predefined electrodes determined the humidity of the medium. The proposed Humidity Sensor at LCLC demonstrates high sensitivity, rapid response and short recovery time. During the project implementation such research methods as: electro-, magneto-optical, photorefractive, dielectric broadband spectroscopy, atomic force microscopy, SEM were used.
