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.
As Lennon and others worked on applications for nitinol, a desire arose to 3D-print complex shapes with it. But that presented a problem: Nitinol and other shape memory alloys conventionally ...
Using heat-activated nitinol metal, researchers have devised a reversible, shape-shifting, conical spiral antenna that needs no discrete external actuator.
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 ...
[Steven’s] at it again with another cool science experiment that isn’t too difficult to do. This time he’s made himself a Nitinol wire inchworm, which actually moves across the table when ...
“Using proprietary shape-memory biocompatible polymers, Embolization’s coil devices achieve better vascular occlusion while ...
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 ...
The use of nitinol, an alloy of nickel and titanium, in prosthetic hands helps achieve faster and smoother finger movements that are similar to human muscles.
A new 3D-printed antenna made from shape memory alloys that changes shape when heated could enable communications over a wider array of radio frequencies.
