The proposed valves and/or fluid pumps are controlled with a piezoelectric actuator, which provides very low power consumption, low cost, very compact designs, high speed response, long life, hysteresis free and linear operation, long displacement over 50 mm and high torque over 400 Newton. A steady continuous flow of a media is achieved by supplying a power profile to the actuator via an electronic circuitry connected to electrodes attached to the piezoelectric actuator.
