A Gecko-Inspired Reversible Adhesive


  • Funding was provided by AFOSR and The Institute of Collaborative Biotechnologies. Fabrication was carried out at Nanotech Nano-fabrication Facility at UC Santa Barbara, part of the National Nanotechnology Infrastructure Network. This work was also partially supported by the IMI Program of the National Science Foundation.

A synthetic, fully reversible, switchable, gecko-inspired adhesive is presented. The biomimetic system is composed of flexible nickel paddles coated with aligned vertical polymeric nanorods. When subjected to a magnetic field, adhesion decreases by a factor of 40. The ability of the adhesive to controllably stick and release from a surface could enable technologies from ubiquitous latching systems to climbing microrobotics.
