Patent ID: 8912447

Claim:
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.
