Liquid metal material science is an emerging area, significantly different from the study of other metals, polymers, composites, ceramics, or naturally-derived materials. Low melting point metals and alloys are set to have a transformational impact on next-generation science and technology including in 3D printing, additive manufacturing, and robotics. Liquid Metals: Preparations, Properties and Applications presents the state-of-the-art in the emerging science of liquid metals. The title illustrates the material properties of liquid metals in a systematic way. The book discusses key topics including the thermal fluid properties of liquid metal and chip cooling; electrical properties of liquid metal in printed electronics and 3D printing; soft material properties of liquid metal and transformable robots; biomaterial properties of liquid metal materials; and healthcare practices. The title offers a multidisciplinary reference to all currently available liquid metal materials and technologies. This volume collates and summarizes major advances in seventeen chapters, and gives examples of liquid metal applications. The handbook brings readers up-to-date with the study of low melting point metals and alloys, and prepares the ground for further investigation and use of these exciting and novel materials.
