Liquid Wire Liquid Wire produce circuitry based on encapsulated Metal Gelâ„¢ which can flow to ensure conductivity when the substrate is stretched or flexed. This conductive Bingham plastic is also used in vias and SMD attachment, thus interfacing between rigid components and flexible/stretchable interconnects. The company is primarily targeting medical/fitness skin patches and e-textiles but have also received interest in many industrial applications. Liquid Wire
