A micro-electro-kinetic actuator (MEKA) array for the control of the viscous sublayer of a turbulent boundary layer is developed. Several generations of MEKA arrays are fabricated that explore the use of non-conventional MEMS materials such as quartz, polymers or mylar and are combined where needed with conventional MEMS design and fabrication process. The potential advantages of using the electrokinetic principle as the basis for a new class of microscale actuators suitable for active sublayer control are also discussed. It is found that the actuators have no moving parts and they achieve the flow rates required for this type of flow control.
