Abstract

The invention provides a method for preparing a transformable robot through composition of a shape memory alloy and liquid metal. The preparing method comprises the steps that a, three metal elements including gallium, indium and tin are mixed evenly according to a certain proportion, and the liquid metal with the melting point ranging from 40 DEG C to 60 DEG C is formed; b, a certain number of magnetic particles are added in the liquid metal; c, the NiTi shape memory alloy is pretreated into a human shape; and d, the liquid metal and the shape memory alloy are compounded, and the transformable robot prepared through the composition of the shape memory alloy and the liquid metal is obtained. The transformable robot is in the human shape under the condition of the room temperature, is changed into the liquid state when being soaked in hot water and can be changed into any shape, and when the transformable robot needs to be restored into the human shape, the material of the composition of the shape memory alloy and the liquid metal is placed in the hot water, and the transformable robot can be restored into the human shape again through electric or magnetic drive. According to the robot with the composition of the shape memory alloy and the liquid metal, the shape memory alloy serves as a framework, the liquid metal serves as muscles, the transformable robot is truly achieved, and important application value is achieved in the new material field, the biomedical field, the engineering field and other fields.

Description

technical field [0001] The invention relates to a method for preparing a deformable robot with a shape memory alloy composite liquid metal, which belongs to the technical field of new materials. Background technique [0002] With the emergence of a large number of multifunctional metals in recent years, scientists' research on liquid metals has also emerged in an endless stream. Liquid metal is an amorphous metal that can be regarded as a mixture of positive ion fluid and free electron gas. The liquid metal mainly contains Ga In Sn elements (Ga67%, In20.5%, Sn12.5% ​​by volume, the components and proportions contained in each are different). Under low temperature conditions, Ga In Sn elements can be fused with many metals, rubber, glass and other substances. This makes the liquid metal composed of GaInSn and its alloys widely researched and applied in the fields of computer research, electrical engineering, energy and medicine. However, the current research on liquid meta...
