Claim 16:
17. An integrated miniature sensor assembly comprising:
a microneedle subassembly operably connected to a sensing element subassembly and configured for nondestructive and minimally invasive in vivo or in situ access to an accessed medium or sample, the microneedle subassembly comprising one or more microneedles, the sensing element subassembly comprising one or more sensing elements,
wherein at least one of the sensing elements comprises an electrode and the electrode is modified with an ion-specific material configured to trap and take one or more measurements of an ionic species related to the ion-specific material in an accessed medium or sample; and
an on-board interface operatively connected to the one or more sensing elements and adapted to communicate the one or more measurements to a measurement circuit.
