The present invention provides a method of manufacturing a 2D or 3D structure of a liquid metal wire of a desired shape by connecting liquid metal wires by room temperature welding, and a 2D or 3D structure of the liquid metal wire manufactured therefrom. According to the present invention, there is no need for any additional metal other than the liquid metal to be used in connecting the liquid metal wire. By continuously connecting two or more liquid metal wires at room temperature without a high energy source required for general metal welding, two-dimensional and three-dimensional structures of liquid metal of desired shapes can be easily manufactured. The method for manufacturing 2D or 3D structures by connecting liquid metal wires of the present invention may include a step of injecting liquid metal into a hollow elastomer fiber, and a step of solidifying the injected liquid metal to produce an elastomer fiber including a solidified liquid metal core. 본 발명은 상온 용접의 방법으로 액체금속 와이어를 연결하여 원하는 형상의 액체금속 와이어의 2D 또는 3D 구조물을 제조하는 방법 및 그로부터 제조되는 액체금속 와이어의 2D 또는 3D 구조물을 제공한다. 본 발명에 의하면 액체금속 와이어의 연결에 있어 사용하고자 하는 액체금속 외에 다른 종류의 추가적인 금속을 필요로 하지 않으며, 일반적인 금속 용접에 있어 필요한 고 에너지원 없이 상온에서 두 개 또는 그 이상의 액체금속 와이어를 연속적으로 연결하여 원하는 형상의 액체금속의 2차원 및 3차원 구조물을 용이하게 제조할 수 있다.
