Other teams have come up with similar devices before, although no one was able to create something that didn’t rely on exotic materials or a complex fabrication process. IBS team stayed away from carbon nanotubes and gold and looked at a more utilitarian option for their build material: thin slivers of silver nanowires ∼150 nm in diameter and ∼30 μm in length (a human hair ranges from 17 – 181 µm). The nanowires were mixed into a liquid elastic material which is both soft and stretchy when dry.
To ensure that the material remains tight on the target area while heating, the team devised a 2D interlocking coil pattern for the mesh structure. To make the mesh, the liquid mixture was poured into a shaped mold...
