Claim 12:
13. An apparatus, comprising:
a band configured to extend at least partially around a body part of a user, the body part comprising a dermal layer;
a user interface coupled to the band;
a processing device coupled to the band;
a miniaturized impedance sensor integrated into the band and positioned in the band to be pressed against the dermal layer adjacent to a subdermal feature, wherein:
a first set of miniaturized electrodes is configured to transmit an electric signal into the body part as the user wears the band; and
a second set of miniaturized electrodes is configured to receive the electric signal through the body part as the user wears the band;
wherein each miniaturized electrode comprises an array of a first miniaturized electrode pillar and a second miniaturized electrode pillar, the first miniaturized electrode pillar comprising a first height greater than a first length or a first width and a first contact surface of the first miniaturized electrode pillar defined by the first length and the first width of the first miniaturized electrode pillar, the second miniaturized electrode pillar comprising a second height greater than a second length or a second width and a second contract surface of the second miniaturized electrode pillar defined by the second length and the second width of the second miniaturized electrode pillar;
an electrical circuit embedded in the band interconnecting the user interface, the processing device, or the miniaturized impedance sensor; and
at least one interstitial filler distributed between the first and second sets of miniaturized electrodes and the first and second miniaturized electrode pillars of each miniaturized electrode set.
