A group of researchers from Carnegie Mellon University have found that they have been used in engineering robotic electronics. Like previous efforts, it involves a certain kind of polymer. Carmel Majidi and his team inserted liquid microdroplets of a gallium-indium based metal alloy into a soft elastomeric shell.
Essentially, it's a solid-liquid hybrid that is stretchable Even if damaged multiple times.
Majidi says the composite material comes from the nervous system's ability to regenerate itself. It is not mimicking neuroplasticity entirely, though; while the metal-elastomer could be useful in wearable computing and inflatable airships to protect against electrical damage, there's no such protection for mechanical or structural damage. That's the eventual aim ̵
