Mechanical engineers at ETH Zurich and Purdue University are trying to mimic God’s design of the wing folds of the humble earwig, a folding structure superior to anything made by humans.
The rigid, straight folds of paper origami can stretch and break, but the earwig’s elastic wing folds are flexible and self-folding. Rather than lacking stability, they lock into specific shapes, allowing the wings to both extend and rotate.
