Abstract
A method includes patterning one or more electrical layers on a substrate; shaping the patterned substrate into a 3-dimensional contour, wherein the contour including a significant change in gradient in or adjacent to one or more sensing areas of the electrical layer, and over-molding the shaped substrate. Degradation of a trace in the electrical layer at or adjacent to the one or more sensing areas during shaping and/or over-molding is substantially minimized based on the width of the trace, the thickness or number of layers of the trace, the bending radius of the trace, the material of the trace, and/or a primer over layer on the trace.

A method comprising:
- patterning one or more electrical layers on a substrate to form a patterned substrate, wherein the one or more electrical layers comprise a trace, and wherein the trace comprises a width, a thickness, a number of layers, and a material;
- shaping the patterned substrate into a 3-dimensional contour, wherein the contour comprises a significant change in gradient in or adjacent to one or more sensing areas of the electrical layer;
- changing a gradient of the trace at the significant change in gradient during the shaping to create a bending radius of the trace;
- over-moulding the shaped substrate, and
- substantially minimising degradation of the trace in the electrical layer at the significant change in gradient during at least one of the shaping, the changing, or the over-moulding based on at least two of:
- the width of the trace, the thickness of the trace, the number of layers of the trace, the bending radius of the trace, the material of the trace, or a primer over layer on the trace.
A method for manufacturing a shaped film, the method comprising:
- applying a functional ink layer on one of a plurality of film layers;
- the functional ink layer having an associated function;
- forming the plurality of film layers into a 3-dimensional shape with a contoured portion,
- contouring the functional ink layer during the forming, wherein the functional ink layer in the contoured portion retains a level of conductivity after the forming such that the function can still be performed after the forming.
