— The background involving the use of liquid‐crystal cells (LCC) in biomedical technologies will be discussed. The possible types of sensors of mechanical vibrations can be constructed on the basis of a highly sensitive liquid‐crystal cell with an initial homeotropic orientation. They are especially effective in the registration of low‐frequency processes such as human breathing. The possible methods of improving the technical characteristics of liquid‐crystal sensors due to the application of an electric field or by using specially designed LCCs will be discussed. Such cells can also be applied to the visualization of breathing.
