Flexible wearable three-lead electrode patch and preparation method and application thereof

The invention relates to a flexible wearable three-lead electrode patch and a preparation method and application thereof, and belongs to the technical field of flexible conductive electrode patches. According to the method, polyvinyl alcohol, zinc acetate, a liquid metal gallium-indium alloy, water and ethanol are taken as main raw materials, the liquid metal gallium-indium alloy and the zinc acetate are taken as conductive components, and are ultrasonically dispersed in a solution to form conductive ink, and the conductive ink is printed on a paper-based material to obtain the flexible conductive electrode patch with excellent conductivity and low skin contact resistance. An acquisition unit of a conductive electrode is printed on a flexible device to serve as an electroencephalogram signal acquisition carrier. The technology not only has the advantages of flexibility, low cost and multiple functions, but also can be widely applied to synchronous monitoring of physiological signals in the movement process. T
