Abstract
Thermomechanical effects in hybrid and cylindrical-hybrid oriented nematic liquid crystals (NLC), as well as thermomechanical effects in NLC with a homogeneous director distribution induced by quasistatic or light electric fields, are observed and investigated theoretically and experimentally. It is postulated that these effects arise from a horizontal hydrodynamic flow in the NLC due to the vertical temperature gradient. There is good agreement between the theoretical calculations and the experimental results. The thermomechanical coefficient is measured. In the case where the hydrodynamic flow tends to strain the curvature of the “flexible ribbon,” an oscillatory motion is observed.
