Assignee: BRIGHAM YOUNG UNIVERSITY
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 15:
16. An apparatus, comprising:
a band configured to extend at least partially around a body part of a user; and
a miniaturized impedance sensor embedded in the band and positioned in the band to be pressed against a region of the body part having a first subdermal feature and a second subdermal feature as the user wears the band, the miniaturized impedance sensor comprising an array of miniaturized electrodes at corresponding locations on the band, wherein the array of miniaturized electrodes is configured to transmit an electrical signal through the body part as the user wears the band, each of the array of miniaturized electrodes positioned on the band at the locations to receive the electrical signal and correspond to the first and second subdermal features of the body part at corresponding depths within the body part,
wherein the miniaturized impedance sensor comprises at least one insulating layer, a conductive layer, a catalyst layer and an interstitial filler; and wherein said miniaturized electrodes are configured in parallel rows; and
wherein the interstitial filler includes a plurality of wells between the parallel rows of miniaturized electrodes configured to:
be flush with a surface of the miniaturized impedance sensor to form a continuous surface, and
allow a dermal feature to flex into the plurality of wells.
