Manufacture of micro-sensors and actuators for flow control

The design, manufacture and testing of micro-sensors and -actuators for aerodynamic drag reduction by flow control is described. Key factors in the designs are discussed, for example, the type and shape of the actuator electrodes affect the critical parameters of frequency response and deflection amplitude. Some aspects of future work are also covered. (c) 2006 Elsevier B.V. All rights reserved.
