Abstract
Disclosed herein is an active roughness actuator and a method of forming an active roughness actuator. The active roughness actuator includes a surface having at least one aperture; a compliant layer disposed on the surface such that the compliant layer covers the at least one aperture; a chamber having a fluid therein and a piezoelectric surface mechanically coupled to the chamber. The chamber is in fluid communication with the compliant layer via the at least one aperture. The piezoelectric surface is configured to displace the fluid in the chamber to control production of at least one dimple in the compliant layer proximate to the at least one aperture.
