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.

It is actually rocket science
Given successful test experiences to date, it is abundantly clear that 3D printing and nickel-containing alloys will be critical to the future of U.S. space travel for decades to come.
