A deformable liquid metal machine that defies gravity

Abstract

The invention discloses an anti-gravity deformable liquid metal machine, and relates to the technical field of flexible machines. By introducing an all-in-one unique material mixing system including a graphite substrate, an electrically controlled liquid metal and the like into electrolyte, the anti-gravity deformable liquid metal machine capable of achieving movement in the anti-gravity direction is firstly provided, the intelligent in-plane deformation capacity of the electrically controlled liquid metal in a traditional glass container is significantly improved, and the machine can be used for preparing a three-dimensional liquid metal deformation body, a flexible actuator, an antenna and a switch circuit, serve as a micro fluid valve, a pump or more artificial machines and control the directional movement and the like of target fluid or sensors.

Description

technical field [0001] The invention relates to the technical field of flexible machines, in particular to an anti-gravity deformable liquid metal machine. Background technique [0002] So far, most robots all function as a kind of rigid body machine. It has been a long-standing dream of the scientific and engineering circles to realize deformable flexible intelligent machines that can freely switch between different forms to perform more special and advanced tasks that are difficult to accomplish with conventional technologies. The corresponding technologies are widely used in military, civilian, medical and It has great theoretical significance and application prospects in scientific exploration. For example, in earthquake relief or military operations, such robots should be able to deform as needed to pass through narrow passages, door cracks, and even gaps scattered in buildings, and then resume their original shape and continue to perform tasks. In the most advanced r...

Problems solved by technology

However, the research team found in the experiment that due to the small magnitude of the electric field force, it is difficult to control the liquid metal through the electrodes, and it is difficult to realize the movement of the liquid metal against the direction of gravity, that is, if the bottom of the container and the ground present even a small angle Finally, it is difficult for liquid metal to crawl under the action of electrodes

This limits the movement dimension of the liquid metal deformation machine to a certain extent
