"Electrically programmable shape-memory actuators that use origami to make arbitrary 3D shapes, including the world's smallest origami bird."

A recent paper published in Science Robotics featured the revolutionary work from the Cohen, McEuen, Muller, and Arias labs. Learn more in this Cornell Chronicle summary

World's smallest origami bird shows potential of nanoscale machines

Cornell researchers have created micron-sized shape memory actuators that enable atomically thin two-dimensional materials to fold themselves into 3D configurations. All they require is a quick jolt of voltage. And once the material is bent, it holds its shape – even after the voltage is removed. As a demonstration, the team created what is potentially the world’s smallest self-folding origami bird.
