Abstract

For airflow control applications, it is necessary to design robust MEMS actuators which could be placed on the wings of aircrafts. In this paper, we concentrate on in-plane actuators that are supposed to be an efficient solution for airflow control, and we present a design which uses a MEMS actuator embedded in a polymer layer which enables its in-plane movement. The knowledge of polymers mechanical characteristics -- and especially their behavior versus frequency -- is necessary for the design of such an actuator. We have determined these characteristics experimentally in order to be able to describe properly the actuator. With these measured values, we have explored two possible designs which are found to produce displacements of a 10 - 20 microns for a 3 mm actuator's total dimensions. Their frequency response is mainly limited to 2 to approximately 5 kHz by the increase of the polymer's stiffness.
