Problems solved by technology

However, the current polyimide material is not flexible enough to meet the above design requirements
[0005] The difficulty of using polyimide as the conductive film material is that the metal component is difficult to sputter or disperse in the polyimide polymer material, and it is difficult to form a conductive structure.
