Engineers have developed a tiny liquid-metal pump that could help make future soft robots, wearable devices, and medical technologies smaller, lighter, and more flexible. The new invention is so compact that it is about the size of a pea, yet it can power robotic movements using less than 0.1 volts of electricity. The technology was […] The post Tiny liquid-metal pump could power the next generation of soft robots appeared first on Knowridge Science Report .
