Abstract
Shape memory actuators are utilized to controllably modify the permeability of fabric and fabric based articles. The SMA actuator operates by changing the geometric permeability or by modifying the weave permeability of the fabric based article, or one or more portions thereof. The invention further provides for applications of the controllable permeability fabric, which include by way of example, various parachute, sail, and filter embodiments.
