Abstract

The invention relates to a channel device for controlling magnetic liquid metal by utilizing electromagnetic field coupling. The channel device comprises a power supply, a magnetic field element and aplurality of channels, wherein the channels are crossed at a branch; an electrolyte solution is arranged in each channel and the branch; a first electrode is arranged in one channel, and second electrodes are arranged in the rest of at least two channels; the first electrode is connected with a negative electrode of the power supply; each second electrode is connected with the positive electrodeof the power supply; when at least two positive electrode circuits are accessed, magnetic liquid metal moves to stop at the branch; after the magnetic field element gets close to the liquid metal, andthe magnetic liquid metal is attracted to an inlet of certain channel, the magnetic field element is removed, and under action of the electric fields, the magnetic liquid metal moves forwards along the channel. Magnetic fields are utilized for assisting magnetic liquid metal to move in the electric fields, and magnetic fields are applied to the bottoms of the channels, so that the magnetic liquidmetal smoothly moves in the target channel.

Description

technical field

[0001] The invention relates to a liquid metal, in particular to a channel device for controlling magnetic liquid metal by electromagnetic field coupling. Background technique

[0002] The electric field is the main way to drive liquid metal, but it is not yet mature for multiple circuits to drive liquid metal at the same time; in addition, in the multi-channel with intersection points, the magnetic liquid metal will only stop at the multi-channel intersection point and cannot continue to move forward; finally, Both magnetic and electric fields can drive magnetic liquid metals, but there are few studies on the simultaneous control of magnetic liquid metals in both ways. Contents of the invention

[0003] The invention overcomes the deficiencies of the prior art and provides a channel device for controlling magnetic liquid metal by means of electromagnetic field coupling.

[0004] In order to achieve the above object, the technical solution adopted by the p...
