It shows remarkable self-healing properties and can be clamped, knitted, and bonded, as shown in a foldable multi-purpose drone, a wearable cast for bone injuries, and a soft multi-directional actuatorVariable stiffness materiallow melting point alloyself-healingshape fixitysoft fluidic actuatorsmultimodal locomotionwearable devicestext::journal::journal article::research article
