How stick insects honed friction to grip without sticking
Date:2/19/2014

stand biological systems, but lessons from nature such as this might also be useful for inspiring new approaches in man-made devices," said Labonte.

He uses the example of a running shoe as a possible man-made item that could be enhanced by stick insect engineering: "If you run, you don't want your feet to stick to the ground, but you also want to make sure you don't slip."

Adds Labonte: "Stickiness is the force that is needed to overcome when trying to detach one thing from another. If the soles of your feet were made of Scotch tape, it may be helpful when you are walking up walls or hanging upside down, but the rest of the time it would be incredibly frustrating."

"Stick insects have developed an ingenious way of overcoming the conflict between attachment and locomotion, with a dual pad system that alternates between stick and grip depending on the situation."
