Researchers at Harvard University's John A. Paulson School of Engineering and Applied Sciences (SEAS) and the California Institute of Technology have developed soft robotic systems inspired by origami that can move and change shape in response to external stimuli.

The researchers used liquid crystal elastomers that change shape when exposed to heat, and utilized three-dimensional (3D) printing to create two types of soft hinges that fold at different temperatures.

The team used its designs to build several soft robotic devices.

Said Harvard’s Jennifer A. Lewis, “The ability to integrate active materials within 3D-printed objects enables the design and fabrication of entirely new classes of soft robotic matter.”
