Abstract
Electrical conductors are disclosed. More particularly, undulating electrical conductors are disclosed. Certain disclosed electrical conductors may be suitable to be disposed on flexible or stretchable substrates.
Claims5
An elongated undulating conductor comprising an axis along a length of the conductor and a plurality of spaced apart first locations, the conductor centered on the axis and defining a plane of the conductor, the conductor having a width between opposing edges of the conductor along a direction parallel to the plane of the conductor, such that along the length of the conductor:
- the axis has a continuous radius of curvature;
- and
- at the plurality of spaced apart first locations:
- the axis has a local minimum radius of curvature, the conductor has a local maximum width and a local maximum thickness, wherein the local maximum width at each first location is greater than the width of the conductor at any other location that is not a first location, the local maximum thickness at each first location is greater than the thickness of the conductor at any other location that is not a first location, and the opposing edges of the conductor curve in a same direction at each of the first and second locations.
A conductor assembly comprising:
- a flexible stretchable substrate stretchable along a first direction up to 1.5 times an original unstretched dimension of the substrate without tearing;
- and
- an undulating conductor disposed on the substrate and generally extending along the first direction, the conductor centered on an axis along a length of the conductor, the axis having a continuous radius of curvature, such that for a plurality of alternating first and second locations along the axis, the conductor is wider and thicker at each first location than at each second location, the conductor having a substantially same width at each first location, wherein each first location corresponds to an area of minimum radius of curvature along the undulating conductor, and each second location corresponds to an area of maximum radius of curvature along the undulating conductor, and opposing edges of the conductor curve in a same direction at each of the first and second locations.
