  1. 1. Geckos By: Rachael Ng
  2. 2. Geckos’ Fiber Structure <ul><li>Geckos have millions of setae, or microscopic hairs, on the bottom of their feet and each of these hairs end with tiny pads called spatulae that help them stick to surfaces– even upside down. </li></ul><ul><li>The setae are small enough that there are weak attractions, called van der Waals forces, between the hairs and the surface, that acts as a strong adhesive but is also very easy to take off. </li></ul>
  3. 3. Self Cleaning <ul><li>Because of their fiber structure, when dirt-clogged hairs are pushed on a surface, they have less contact with the dirt particles than with the surface, so the dirt particles are left behind, stuck to the surface. </li></ul><ul><li>This is possible because the adhesion strength is proportional to the contact area. </li></ul>
  4. 4. Uses Applications of the mimicry of gecko setae
  5. 5. Surgical Dressings <ul><li>Band aids that stay on for a long time and don’t hurt when you take them off. </li></ul>
  6. 6. Tape <ul><li>The gecko setae cleans itself every time it sticks to something so the hairs on this tape are always clean and you can keep on using it over and over again. </li></ul>
  7. 7. Climbing shoes <ul><li>Gecko setae can also be used to make climbing shoes/equipment. </li></ul>
  8. 8. Climbing robots <ul><li>Mark Cutkosky, a professor of mechanical engineering at Stanford, was the lead designer of Stickybot, a reptile like robot that uses gecko setae to scale flat surfaces. </li></ul>
  9. 9. Climbing suit <ul><li>And maybe…a suit that lets humans scale buildings!!! </li></ul>
