Claim 18:
19. A method of monitoring a wearable item, wherein the wearable item comprises:
a flexible base material forming at least a portion of the wearable item; and
a first set of conductive traces and a second set of conductive traces traversing the flexible base material, wherein the first set of conductive traces and the second set of conductive traces follow indirect paths across the flexible base material, such that a conductive trace traversing the flexible base material from a first point to a second point has a trace length which is greater than a direct distance between the first point and the second point,
the method comprising the steps of:
applying a test current to the first set of conductive traces;
detecting a current flow in the second set of conductive traces;
controlling a set of trace connection switches, each trace connection switch arranged selectively to couple a pair of conductive traces comprising a first conductive trace of the first set of conductive traces and a second conductive trace of the second set of conductive traces; and
generate a conductivity indication for the pair of conductive traces.
