WebJul 15, 2006 · Geckos may represent the world’s most demanding adhesives application. The adhesive setae on the toes of climbing geckos must adhere strongly yet avoid fouling or attachment at inappropriate times. We tested the hypothesis that gecko setae are non-adhesive in their unloaded default state by comparing the water droplet contact angle (θ) … WebJun 13, 2007 · We discovered that the energy required to detach adhering tokay gecko setae ( Wd) is modulated by the angle ( θ) of a linear path of detachment. Gecko setae resist detachment when dragged towards the animal during detachment ( θ =30°) requiring Wd =5.0±0.86 (s.e.) J m −2 to detach, largely due to frictional losses. lawndale high school school districtWebEvidence for self-cleaning in gecko setae W. R. Hansen*† and K.
