Elastic conductor and preparation method thereof

The invention discloses an elastic conductor and a preparation method thereof. The elastic conductor comprises an elastic base body and liquid metal, wherein the elastic base body is non-conductive, and the liquid metal is attached to the surface of the elastic base body and is in a continuous spiral winding shape on the periphery of the elastic base body. The elastic conductor is prepared by adopting a torsion forming process. When the elastic conductor is stretched and deformed, the resistance change rate is small, and the elastic conductor has potential application value in flexible electronic devices. 本发明公开了一种弹性导体及其制备方法。该弹性导体包括弹性基体与液态金属，弹性基体不导电，液态金属附着在弹性基体表面，并且在弹性基体外围呈连续的螺旋绕行状。本发明采用扭转成形工艺制备该弹性导体。该弹性导体进行拉伸形变时，电阻变化率较小，在柔性电子器件中具有潜在的应用价值。
