<p>A three-dimensional active composite membrane (M), formed of two layers of polymer (100) and a reinforcement wire net (110) therebetween, actuated to assume selected different three-dimensional patterns (shapes) by an external Shape Memory Alloy (SMA) wire net (120) or by other types of mechanical actuators to which it is attached. More particularly, the composite membrane (M) comprises two elastic outer layers (100) and a reinforcement member (100) extending therebetween. The edges of the reinforcement member (110) are attached through one of the outer layers (100) to edges of an outer Shape Memory Alloy actuating net (120) which has an area similar to that of said reinforcement member (110) and smaller than that of said outer layers (100). The actuating net (120) is driven to contraction or extension by direct heat thereby causing a normal deflection of the reinforcement member (110) and thus of said outer layers (100).</p> |
