Observation of the direct flexoelectric effect in nematic liquid crystals
Yablonskii S. V. , Blinov L. M., Pikin S. A.
It is found that an electric current associated with flexoelectric and electrokinetic phenomena is generated in a pulsating flow of a liquid crystal in the nematic phase. The flexomodulus and the energy of binding of the liquid crystal with the substrate are calculated from the flexoelectric contribution.
