Geckos may use static electricity to stay sticky

Geckos, long thought to use van der Waals forces and tiny toe hairs to stick to surfaces, may also use electrostatic forces.

Research from the University of Waterloo has debunked a long held belief that static electricity plays no part in gecko adhesiveness, based on a study from the 1930s.

The current study used a variety of surfaces and measuring the electrical charge of the gecko’s footpad to conclude that while van der Waals forces do play a part - so does static electricity.
