Stretchable Circuits Made of Liquid Metal Islands

Jun-17-18 Printable, stretchable circuits made of gallium and indium could have applications in wearable and biocompatible electronics.

The metal-polymer conductor (MPC) was created by depositing ‘globs’ of gallium and indium inside a silicon-based substrate, resulting in liquid metal islands within the polymer. A liquid metal base beneath the structure ensures full conductivity, resulting in an MPC able to power devices such as sensors for keyboard gloves and electrodes able to stimulate DNA passage through live cell membranes.

According to the team, the research could lead to more evolved soft robots, as well as medical implants that can diagnose and treat disease—particularly cardiovascular diseases.
