The gallium-based liquid metals are appealing conductor for application in soft and stretchable electronics due to metallic conductivity while they are strained. The liquid metals spontaneously form the thin oxide layer (~3 nm) upon exposure to the oxygen. This oxide layer allows the metal to adhere to various substrates and to stabilize the shape in the air. Utilizing the oxide layer and fluidic property, the liquid metal can be patterned into the desired geometries by microfluidic injection, printing and molding. By utilizing liquid metal inclusions, the soft materials can manipulate the shape and function with metallic conductivity. In this presentation, we will discuss recent emerging applications of the gallium-based liquid metals such as soft, stretchable shape memory polymers with electrical conductivity, thermo- and mechanochromic fibers, stretchable sensors and reversible actuation of surface topography of the dielectric substrates. |
