Abstract

The invention discloses a frequency-adjustable stretchable liquid metal antenna which comprises a stretchable base plate, wherein a curve-shaped liquid metal micro-flow way is machined on the stretchable base plate, and the liquid metal micro-flow way is internally filled with liquid metal or liquid metal alloy; when the stretchable base plate is transversely stretched, the liquid metal or the liquid metal alloy in the curve-shaped micro-flow way is lengthways and transversely deformed, and the length change of the stretched liquid metal antenna is controlled by presetting the proportional relation between the lengthways deformation and the transverse deformation, so that the work efficiency of the transversely-stretched liquid metal antenna can be adjusted. The invention further provides a manufacture method of the frequency-adjustable stretchable liquid metal antenna. According to the frequency-adjustable stretchable liquid metal antenna and the manufacture method of the liquid metal antenna, the length change of the stretched liquid metal antenna is controlled by presetting the proportional relation between the lengthways deformation and the transverse deformation, so that the work efficiency of the transversely-stretched liquid metal antenna can be adjusted.

Description

technical field [0001] The invention relates to the field of flexible electronics manufacturing, in particular to a stretchable liquid metal antenna with adjustable frequency and a preparation method thereof. Background technique [0002] Liquid metal antennas are an important development trend of current radio frequency antennas. In many cases, they have unique advantages and excellent deformation properties. The length of the antenna can be changed during the stretching process and the antenna can still be connected. At the same time, the liquid metal antenna can recover very well after being stretched. If a breakpoint occurs during a certain stretching process, it can be relaxed and the antennas are connected together again, which has good self-repair ability. The liquid metal antenna can be attached to the surface of the object, and can maintain communication with the complex deformation of the object. It will be more widely used, and will gradually penetrate into variou...
