Nitinol, a common shape memory alloy made from nickel and titanium, is an obvious choice, but it’s not obvious how you’d make a shape-changing antenna out of nitinol wire.
But that presented a problem: Nitinol and other shape memory alloys conventionally require extensive mechanical processing—known as cold work—to achieve the shape memory effect, and as a ...
After extensive experimentation toward the antenna application, the team altered the ratio of nickel and titanium, but the first attempt to create a shape-shifting horn antenna using 3D-printed ...
The shape of an antenna’s front end dictates many of its operating parameters. Once it’s manufactured, those characteristics are locked in. A shape-changing antenna would enable communications ...
As a result, they’re typically only available as wire or in thin sheets. ... However, the first attempt to create a shape-shifting horn antenna using 3D-printed nitinol fell short.
He’s also made a great video explaining how Nitinol wire works, and how to use it: And if your interested in making one yourself, he’s planning on releasing a how-to video shortly — stay tuned!
“Using proprietary shape-memory biocompatible polymers, Embolization’s coil devices achieve better vascular occlusion while ...
The difference between the loaded wire and the released wire can be as much as 20° C (36° F). The cooling device is thus quite simple in concept. It uses a rotating cylinder covered in nitinol ...
The use of nitinol, an alloy of nickel and titanium, ... Nitinol Wire in a Prosthetic Hand Makes It Move Like a Human Hand. by Julia Samuel on Mar 25 2015 6:37 PM.
The shape of an antenna’s front end dictates many of its operating parameters. Once it’s manufactured, those characteristics are locked in. A shape-changing antenna would enable communications across ...
