  • Method and apparatus for controlling diaphragm displacement in synthetic jet actuators
    Patent number: 8290724
    Abstract: A method for calibrating a synthetic jet ejector is provided. The method includes (a) taking a first measurement DCR0 of the DC resistance of the coil; (b) adjusting the actuator drive voltage Vd to achieve a desired maximum displacement dmax1 at a frequency f1; (c) measuring the input current Iin and input voltage Vin; (d) calculating the back electromagnetic frequency BEMF, wherein BEMF=Vin?Iin*DCR; and (e) storing the calculated value of BEMF in a memory device associated with the synthetic jet actuator.
