Stretchable conductor circuit
This disclosure provides a stretchable conductor structure, a garment with a stretchable conductor structure, and a method for producing a stretchable conductor structure. The conductive structure includes a set of conductive wires and a stretchable laminate. The set of conductive wires, each including a protective surface, the set of conductive wires patterned in a mesh structure to accommodate a manipulation while providing electrical conductivity across the set of conductive wires. The stretchable laminate encapsulates the mesh structure, the stretchable laminate can return the mesh structure of the set of conductive wires to an original state after the manipulation.
1. A method for producing a flexible and stretchable conductor structure comprising:
applying a protective surface to each of a set of conductive wires;
patterning the set of conductive wires into a mesh structure that accommodates a manipulation while providing electrical conductivity across the set of conductive wires; and
encapsulating the mesh structure in a stretchable laminate such that the stretchable laminate encloses the mesh structure embedded inside of the stretchable laminate, in a manner that the stretchable laminate returns the set of conductive wires to the mesh structure of the set of conductive wires to an original state after the manipulation.
2. The method of claim 1 , further comprising stretching the mesh structure in direction at an equal angle from a weft direction and a warp direction.
3. The method of claim 2 , further comprising returning the mesh structure to an original form after the stretching by the stretchable laminate.
