Liquid metal networks as an ideal platform for stretchable electronics

Thu, 10/03/2019 - 15:58
A novel and very promising design strategy for stretchable electronics is based on liquid metals; specifically the use of the oxide shell of liquid gallium alloys to fabricate polymerized liquid metal networks (Poly-LMNs). The novel attribute of these Poly-LMNs is that they increase in conductivity as they are elongated, resulting in the measured resistance across the conductor remaining nearly unchanged as they are stretched to 700% their original length. The implication of this effect is that a circuit can now be designed with a stretchable Poly-LMN wire that won?t change its resistance when stretched.
