Carnegie Mellon Gecko Adhesive Commercialized

Posted By ASC, Thursday, September 24, 2015

NANOGRIPTECH, a spinoff from Carnegie Mellon University, has commercialized an adhesive based on the sticking power of geckos. Their flagship product, Setex, is the first gecko-inspired adhesive to be commercialized, and can be used repeatedly without losing stickiness. Setex is composed of elastomeric film with millions of microfibers that can conform and adhere to surfaces. The adhesive production process is proprietary, but it requires clean-room technology and techniques adapted from the semiconductor industry. The process is scalable because an original cleanroom template must be made, but subsequent manufacturing is relatively inexpensive. Currently there are three forms of Setex. The first is Setex-dA, a single-sided dry adhesive that comes on a roll much like traditional adhesive tapes. The second is Setex-cF, which is double sided and functions like a Velcrow that will only fasten to a specific “mating” surface. Finally the third is Setex-xG, a gripping, friction material likely to be useful in sports equipment or prosthetics.
