Simulation of velocity profiles of electric-fields induced nematic liquid crystalline flows between parallel plates has been achieved using the Leslie-Ericksen theory, as the fundamental research on the development of liquid crystalline micro-actuators. To obtain continuous movement of the micro-actuators, the pulsated electric field is applied on the nematic liquid crystal cell. The various frequencies of the applied electric filed are examined to explore the effect of the frequency on the movement of the cell upper plate. Responding to the pulsated electric field the director angle increase and decrease repeatedly. The clockwise and counter-clockwise rotational motion of the director induces forward and backward movement of the cell upper plate. When the frequency is high, smooth movement of the upper plate is obtained, apparently.
