Assignee: BIOLINQ INCORPORATED
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 10:
11. A skin-adorned sensing device comprising:
a die stack mounted on a printed circuit board, the die stack comprising:
a first substrate comprising:
an array of microneedles configured to sense an electrophysiological or electrochemical reaction within physiological fluid or tissue; and
a first conductive conduit in electrical communication with a first microneedle of the array of microneedles and extending through the first substrate; and

a second substrate comprising:
a second conductive conduit extending through the second substrate and longitudinally aligned with the first conductive conduit,
wherein the first conductive conduit and the second conductive conduit are configured to provide electrical communication between the first microneedle of the array of microneedles and the printed circuit board,
wherein a posterior surface of the second substrate comprises a CMOS circuitry transducer; and
wherein the device is configured to interpret a signal produced by an electrophysiological or electrochemical reaction occurring at the first microneedle of the array of microneedles to determine a level of a physiological or biochemical entity.
