We have performed the experimental investigation on macroscopic electric polarization of a liquid crystal under shear flow between concentric cylinders. The liquid crystal is filled between the concentric cylinders, and sheared by rotating the inner cylinder. We successfully measured the voltage between the cylinders induced by the liquid crystal during the shear flow. From the result, it is found that the voltage profile is pulse-like and irregular, and its maximum value is about 70 mV for 0.202 rpm of inner cylinder revolution. In addition, the maximum value of the voltage increases with increasing the inner cylinder revolution.
