Researchers have developed multifunctional origami structures, which they then fabricated into 4D printed objects. The design principle mimics the structure of an earwig’s wing. When open, the earwig wing expands 10X larger than when closed – one of the highest folding ratios in the animal kingdom. The large wing area allows the insect to fly, while the compact way the wings retracts enables the creature to tunnel underground without damaging its wings. The wing design has another unique feature; however, in its open, locked state the wing remains stiff with no need for muscle power to provide stability. With just one “click,” the wing folds into itself completely, without muscular actuation.

Researchers at ETH Zurich and Purdue University have been studying the secret of the earwig’s ori...
