Adhesion in gecko setae is a … WebFeb 1, 2005 · Although self-cleaning by water droplets occurs in plant and animal surfaces, no adhesive has been shown to self-clean. In 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. WebThe gecko-inspired self-cleaning synthetic adhesive is described in a paper appearing online in Langmuir (Sep. 2008). The paper demonstrates for the first time a synthetic …
