Abstract:
1. A method of employing an adhesion device for releasably holding an object to a surface comprising: providing an anchor portion having one side thereof to be affixed to a part of an object to be releasably adhered to the surface; providing a peeler layer made of a flexible material and having an inwardly facing side thereof affixed to an opposite side of the anchor portion; and providing a “biomimetic microstructure adhesive” (BMA) portion affixed to an outwardly facing side of said peeler layer with its setae facing outwardly towards the surface to be adhered to, and positioning said anchor portion at a position that is laterally offset from a position at which the BMA portion is affixed, so that when said anchor portion is lifted to remove the object from the surface, said anchor portion pulls on the laterally offset position of the flexible peeler layer to thereby start pulling first on an initial set of setae of said BMA portion proximate to the offset position of the anchor portion causing said initial set of setae to be pulled at a force-reducing inclined detachment angle from the surface and passing the pulling force on said anchor portion at the laterally offset position on to successive setae in turn to thereby reduce the overall pulling force required to remove the BMA portion from the surface and thereby make release of the object easier.
