Wrinkles aren’t just for raisins and soggy fingertips.
A team of MIT scientists has figured out how to create perfectly ordered furrows and folds that could be used for stretchable electronics, sticky surfaces or antireflective coatings. The new wrinkling method uses a special stretching technique to form microscopic zigzags, researchers report in an upcoming Advanced Materials.“There are dozens of possibilities,” for the miniature wrinkles, says mechanical engineer and study coauthor Mary Boyce. Her team wants to use the herringbone designs to make antifouling coatings — films that can be used to block bacterial buildup on medical devices like catheters and stents.
