Soft finger-like robots can sweat to cool down just like humans

Robots are becoming more human-like every day: now they can sweat. Thomas Wallin at Cornell University in New York and his colleagues have created soft robotic grippers that are capable of sweating to cool down. The grippers are capable of a cooling capacity of 107 watts per kilogram, making them more efficient sweaters than mammals. By comparison, humans and horses have a maximum cooling capacity around 35 watts per kilogram. Each gripper consists of three finger-like parts that bend simultaneously to grasp small objects.
