Abstract
A conductive trace residing on a stretchable medium, whose geometry in terms of one or more of width, thickness, material stack-up, and other properties are varied along the trace to reduce changes in trace resistance when the medium is stretched. In some embodiments, the geometry is arranged to encourage increased bending in selected regions of the trace to allow stretch deformation of the trace at least partially by elongation rather than entirely by dimensional deformation, thereby reducing conductivity change due to changes in cross-sectional area.
Claims22
A stretchable conductive trace, comprising;
- a. a first stretchable substrate;
- and,
- b. a second substrate including a stretchable conductive material;
- wherein the trace modulus is varied along the trace geometry to increase bending in lower modulus regions relative to higher modulus regions when the first substrate is stretched.
