the wikipedia page for nitinol is fascinating! so it seems like very much part of modern materials science. (and I'd guess bimetals are standard in many heat-related engineering applications, nitinol is just special because of how fast it changes shape, and because it's an alloy not 2 pieces of metal stuck together.) https://en.wikipedia.org/wiki/Nickel_titanium#Biocompatible_and_biomedical_applications https://en.wikipedia.org/wiki/Nickel_titanium#Biocompatible_...
