Can we keep robots cool by making them sweat?

Researchers have developed a method to cool robot motors using hydrogel materials that mimic perspiration. These materials contain water and cool quickly when temperatures exceed 86 degrees. The base layer shrinks, pushing water to the top layer, which has pores that release water to evaporate and take heat away. To address potential slipperiness from this 'Robo sweat,' researchers are working on surface modifications like fingerprint-like ridges to improve grip.
