Gecko-Inspired Tape Can Be Reused Thousands of Times

Zothecula writes "As is so often the case these days for those searching for a better way to stick stuff together, researchers from the Zoological Institute at the University of Kiel in Germany have turned to the biology of gravity-defying ceiling walkers, such as geckos and insects. These creatures served as inspiration for a new dry adhesive tape that not only boasts impressive bonding strength, but can also be attached and detached thousands of times without losing its adhesive properties."

My hypothesis is the smaller particulate matter doesn't present enough surface area to accumulate the force required to move it. In order for the gecko to cling to something the ratio of surface area in contact with the pads to mass must exceed some threshold.
