Inspired by earthworms, new breathing material lubricates itself when needed

Earthworms are always clean, even if they come from moist, sticky soil. They owe this to a dirt-repellent, lubricating layer, which forms itself again and again on its skin. Researchers at INM have now artificially recreated this system of nature: They developed a material with a surface structure that provides itself with lubricant whenever pressure is applied. Because the lubricated material reduces friction and prevents the growth of microbes, scientists can envision numerous applications in ...
