Shape memory alloy valve
WebbA valve apparatus employs a shape memory alloy. In another aspect, a shape memory member acts as a lock or trigger in combination with a separate actuator or spring to move a valve. Still another aspect uses an externally mounted shape memory member to rotate a valve if an unsafe condition causes movement of the member. WebbCurrently, the only smart materials with a significant clinical impact in cardiovascular implant design are shape memory alloys, particularly Nitinol. Recent prodigious progress in material science has resulted in the development of sophisticated shape memory polymers. In this article, we have reviewed the literature and outline the ...

Webb27 dec. 2013 · A Shape Memory Alloy (SMA) is able to memorize and recover its original shape, after it has been deformed by heating over its transformation temperature. This unique effect of returning to an original geometry after a large inelastic deformation (near 8%) is known as the shape memory effect (SME). Webb21 juli 2024 · Shape Memory Alloy valves can be used in space for reducing the risks of spacecraft break-ups. ESA is investigating in SMA valves that could be activated at the end of the missions to vent all the remaining propellant. The number of debris in orbit requires an urgent reaction if we want to keep benefiting from it.
