Non-Slip Footwear & Cross Country Skiis Stick to Ice

In another configuration, PETD can increase the friction between ice and other objects such as shoes or tires, creating “ice brakes.”

The same concept of applying short pulses of electricity directly to an ice-material interface can also be used to control whether ice is sticky or slippery. Electronic friction control for winter sports equipment—serving as electronic brakes or "electric wax"—is thus another application for Petrenko's ice-control technology http://engineering.dartmouth.edu/research/engineering-innovation-for-ice-adhesion-and-friction-control/
