Researchers are looking to insects – specifically cicadas – for insight into the design of artificial surfaces with de-icing, self-cleaning and anti-fogging abilities.Their wings allow cicadas to fly, of course, but they also are good at repelling water – a condition that humans can appreciate, too. “Our work with cicadas is letting us explore a field called bioinspiration,” said Nenad Miljkovic, a University of Illinois mechanical science and engineering professor who co-led a new study of cicada wings.

“We are learning as much as we can from the natural design of cicada wings to engineer artificial objects that are useful to humans...

Stretch-and-release fabrication, testing and optimization of a flexible ceramic armor inspired from fish scales,” by Robert Martini and François Barthelat, Bioinspiration and Biomimetics: http://iopscience.iop.org/article/10.1088/1748-3190/11/6/066001

Ceramic-covered gloves offer industrial workers increased protection from piercing. They started with striped bass. Over a 2-year period the researchers went through about 50 bass, puncturing or fracturing hundreds of fish scales under the microscope, to try to understand their properties and mechanics better. “The people at the fish market must have wondered what we were up to,” says François Barthelat smiling ruefully...
