We’ve all probably used tape or other adhesives before. As useful as they are they often loses their effectiveness over time because of dust or other debris under it. Well, what if I told you that there was a solution to this? Now, what if I told you that the answers came from a frog?
Science Daily article “Tree Frogs' Self-Cleaning Feet Could Solve a Sticky Problem”, talks about the sticky pads on tree frogs’ feet that allow them to climb with ease. Normally you’d expect these pads to get dirty and loss their effectiveness. Well they don’t and researchers have found out why. It turns out that as these frogs climb they secrete extra mucus which not only increases adhesion, but also cleans the frogs’ feet as they move. These tree frogs also have patterns on their feet that allow parts of their feet to always be touching the surface while they secrete the mucus via channels between these patterns.
Using these principles could allow the creation of reusable, effective adhesives for humans, particularity bandages. There are already adhesives made from designs inspired by geckos and their amazing climbing abilities, according to Science Daily. I’ve always been interested in amphibians and reptiles. Discoveries such as these make me glad that I choose to take herpetology this semester.
