WebSelf-cleaning occurred in arrays of setae isolated from the gecko. Contact mechanical models suggest that self-cleaning occurs by an energetic disequilibrium between the … 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.
