Electrostatic Gecko Mechanism
Journal Title: Tribology in Industry - Year 2009, Vol 31, Issue 1
Abstract
Nanoparticles (NPs) are ubiquitous and attach to all surfaces. Nature by providing the gecko with toe-hairs to detach NPs from surfaces has allowed electromagnetic (EM) radiation to be produced that by the photoelectric effect allows the gecko to walk on walls and ceilings by electrostatic attraction. Since attached NPs are a part of macroscopic surfaces, the atoms in the attached NPs are not under EM confinement and are allowed by quantum mechanics (QM) to have full thermal kT energy. But NPs in the detached state differ in that they are under EM confinement at vacuum ultraviolet (VUV) levels that by QM are restricted to vanishing kT energy and specific heat, and therefore the full kT energy remaining cannot be conserved by an increase in temperature. Since NPs have EM confinement frequencies at VUV levels, and since the EM confienement frequency is the lowest frequency allowed in the NPs, the low frequency excess kT energy is frequency up-converted to the VUV by quantum electrodynamics (QED). Conservation is completed by the NPs emitting a burst of VUV radiation that by the photoelectric effect charges the walls and ceiling positive and the toe-hairs negative, therby allowing the Gecko to walk on walls and ceilings by electrostatic attraction.
