With the help of nanotechnology, SMAs such
as Nİ-Tİ-Al-Zn, Cu-Ni-Ti and Cu-Al-Zn can be used as fillers in microchips.
Although SMAs raise the cost, they make better conductor than traditional
fillers which is necessary for us to produce more improved microchips.
Researchers at University of Oxford developed
a tiny device made up of SMA that will help brain aneurysm treatment. The
device is made from a special laser-cut SMA and will serve as a catheter during
surgeries. Device can fit into natural shape of blood vessel. Therefore blood
will be diverted away from aneurysm and will allow it to heal.
A new development at Florida Atlantic
University (FAU) may be the future of prosthetic devices. By using a
heat-sensitive SMA which will bend as a response to core of the finger. Using
3D printers two SMA plates are made and positioned. One them flexes in response
to heat and other does the opposite. This contrast between plates makes the
device work in harmony. On these grounds, device looks promising to be used as the
material of prosthetic devices in the future.
German engineers used thin SMA to form a
mechanism of an artificial hand. The thin SMA wires will work like fibers in a
muscle of human arm. Similar to prosthetic finger in FAU this material, Ni-Ti
alloy in this case, is heat-sensitive and it responses the heat produced by the
electric current which flows through the SMA wires.
