With both metallic properties and fluidic behaviors that can easily switch between liquid and solid phases at room temperature, the liquid metals and their allied soft matters are quickly emerging as powerful materials in diverse areas. Owning dramatic capabilities, the liquid metals family is rather big spanning from those already partially tackled gallium, bismuth and their alloys to more related materials. Over the past two decades, the material categories and the soft sciences lying behind the liquid metals have been significantly expended and many intriguing findings were kept achieved. In this talk, I will first present several basic forms of liquid metals such as functionalized liquid metal composites, liquid metal bubbles or vacuoles, porous liquid metals, liquid conductor-insulator transition materials and colorful liquid metals etc. Then I will explain the fundamental soft sciences to realize and utilize such materials and discuss the soft electronics, multi-phase physics of liquid metal flows, fluidic magnetism and soft chemistry. Following that, I will illustrate some technological and industrial examples regarding thermal management, printed electronics and semiconductors, healthcare and transformable robotics. Lastly, perspective on the liquid metal soft sciences will be given. It can be seen that liquid metals will witness huge opportunities to tackle more and more technological challenges and play ever important roles for the coming society.
