Claim 11:
12. An apparatus, comprising:
a layered miniaturized impedance sensor, comprising:
a patterned conductive layer, wherein a conductive layer pattern comprises regions of conductive material adjacent to regions of non-conductive material, wherein:
regions of conductive material are spaced from each other to prevent capacitive coupling and arcing between the regions of conductive material; and
the patterned conductive layer is conductive of an electrical signal to or from a miniaturized electrode;

an insulating layer disposed on the patterned conductive layer;
a patterned catalyst layer, wherein a catalyst layer pattern is aligned with the conductive layer pattern;
a patterned array of miniaturized electrodes, wherein a miniaturized electrode pattern is aligned with the conductive layer pattern or the catalyst layer pattern; and
an interstitial filler disposed between individual miniaturized electrodes of the patterned array of miniaturized electrodes; and

a substrate, wherein:
the layered miniaturized impedance sensor is attached to the substrate;
the substrate comprises a shape and flexibility to integrate the substrate and the layered miniaturized impedance sensor into a wearable device;
the substrate comprises an interstitial filler;
the interstitial filler comprises a rigid material and a flexible material;
the rigid material is disposed within subsets of the patterned array of miniaturized electrodes; and
the flexible material is disposed between the subsets of the patterned array of miniaturized electrodes.
