Liquid metal refers to metals that are in a liquid state at or near room temperature. One of the most well-known examples is mercury, which is the only metal that remains liquid at standard conditions. Liquid metals can exhibit unique properties, such as high thermal and electrical conductivity, making them useful in various applications. In recent years, researchers have explored the potential of liquid metals in technology, particularly in soft robotics and electronics. These materials can be manipulated easily, allowing for flexible designs and innovative solutions in fields like medical devices and energy storage. Their unique characteristics continue to inspire advancements in material science.
