A team of scientists has created a new type of soft electronics with new skin-like soft and elastic circuits. It turned out that they withstand numerous damage under load without losing conductivity.
Modern consumer devices such as phones and laptops contain rigid materials that use soldered wires. New soft circuits are replacing these inflexible materials with soft electronic composites and tiny electrically conductive droplets of liquid metal.
This approach allows the electronics to be reused: all the connections in the circuits can be dissolved and started over. The circuits are soft and flexible like leather. They are able to continue working even with severe damage.
In the production of such flexible composites, liquid metal droplets are applied to an elastic polymer, which makes it possible to quickly customize circuits by selectively connecting the droplets. In addition, this technology allows you to locally break droplets into smaller ones, creating new contours and connections.
Such soft electronics are part of a rapidly evolving field of technology that gives gadgets a level of ruggedness that was not possible just a few years ago. Although a resilient smartphone has yet to be created, rapid development in this area also promises wearable electronics and soft robotics.
