Claim 3:
4. The wearable item as claimed in claim 1, wherein the plural conductive traces comprise a third set of conductive traces and a fourth set of conductive traces, and wherein:
the driver circuitry is configured to apply a further test current to the third set of conductive traces;
the readout circuitry configured to detect a further current flow in the fourth set of conductive traces; and
the control circuitry is configured to control a further set of further trace connection switches, each further trace connection switch arranged selectively to couple a further pair of conductive traces comprising a third conductive trace of the third set of conductive traces and a fourth conductive trace of the fourth set of conductive traces,
wherein the conductivity sensing circuitry is configured to generate a further conductivity indication for the further pair of conductive traces.
