Origami- and kirigami-based metamaterials have applications from robotics to medical devices.
The ancient arts of origami, the art of paper-folding, and kirigami, the art of paper-cutting, have gained popularity in recent years among researchers building mechanical metamaterials. Folding and cutting 2D thin-fi...

Rice University graduate students Faye Yap, left, and Zhen Liu characterize a mask sample. Researchers at Rice and the University of Texas Medical Branch, Galveston, have established a framework for properly decontaminating disposable facemasks. They determined that heating a mask in a 160-degrees-Fahrenheit ...

Modeled after an earthworm, Meshworm is a soft autonomous robot that moves via peristalsis, crawling across surfaces by contracting segments of its body.
Earthworms creep along the ground by alternately squeezing and stretching muscles ...

Researchers at the University of Pennsylvania and MIT have genetically engineered muscle cells to flex in response to light, which may one day enable highly articulated, flexible robots.
Many robotic designs take nature as their muse: st...
