Moths' invisibility cloaks evade biosonar predators.
Researchers from the University of Bristol and Diamond Light Source have discovered how moths create a powerful stealth cloak preventing detection by biosonar. By harnessing the ingenious properties of moth wings, a sound absorber can be created that offers high absorption with minimal space requirements. The goal is to improve living conditions as such moth-inspired sound absorbers can be 90% thinner and lighter than existing solutions, bringing exotic materials like sound-absorbing wallpaper in reach.
