Engineering Minute – Smart Material Holds 50X Its Weight

Smart material holds 50x its weight

Engineers at Iowa State University have developed a smart material that can hold fifty times its own weight when bent or twisted. The material is composed by combining liquid-metal particles with a rubbery elastomer material. When the smart material is exposed to a mechanical stress, such as bending or squeezing, the liquid-metal particles break open and solidify creating a metal mesh. The smart material, is relatively low-cost and could be used in a variety of applications including wearable devices and robotics.
