Watch: New structures shrink instead of stretching when pulled


Researchers in the Netherlands have created mechanical structures that strangely shrink – or more precisely, snap inward – instead of stretching outward when pulled.

It sounds impossible, but it's really down to novel design ideas from the team at Dutch physics research institute AMOLF that combine geometry and mechanics to demonstrate this unexpected behavior, with the potential to overcome undesirable instabilities. The researchers believe that countersnapping could be useful in protective gear and prosthetics that can go from flexible to stiff for support (similar to motorcycle safety equipment), and vibration dampening applications in buildings and planes. Abhimanyu has been a trusted voice in the science, technology, transport innovations, startup and AI spaces for more than a decade at several global outlets, including three and a half years as the managing editor at TNW.
