Researchers at North Carolina State University are using nickel-titanium shape memory alloys to create a new generation of remote-control flyers

No longer mere curiosities, nickel-titanium shape memory alloys (SMAs) are being used in industrial applications, such as in bridges in earthquake-prone regions (as discussed in our December 2009 issue), while, at the research level, scientists continue to explore their potential in new – and sometimes strange – ways.

Case in point: researchers at North Carolina State University are using SMAs to develop robotic bats which, thanks to their maneuverability, should be able to perform search-and-rescue functions in collapsed buildings and other enclosed spaces.

Nickel alloys helping hearts beat stronger
With an aging population, demand is stronger than ever for pacemakers and defibrillators. With increased usage of Magnetic Resonance Imaging (MRI), it is important that permanent implants are made from non-magnetic materials, such as UNS R 30035.
