Abstract: The present disclosure relates generally to biodegradable sensors for biomedical applications, and more particularly to a wirelessly interrogatable, bioresorbable sensor for postoperative monitoring of physiological parameters. A sensor system includes a substrate, an electrode layer disposed on the substrate, the electrode layer including a split-ring resonator coupled to at least one interdigitated capacitor, wherein the at least one interdigitated capacitor is connected in series with the split-ring resonator, a passivation layer disposed on the electrode layer, and a sensing film disposed on the passivation layer, wherein the sensing film is configured to change in thickness in response to an analyte of interest, and wherein a change in thickness of the sensing film causes a shift in a resonance frequency of the sensor system.

Abstract: An apparatus for monitoring a bioprocess parameter. The apparatus includes: a housing; a bioprocess sensor attached to an outer surface of the housing; a power supply contained within the housing; and an electronics module contained within the housing and in communication with the power supply and the sensor, where the electronics module includes a wireless communication unit.

Abstract: The present invention relates to a device and method for monitoring internal pressures and pressure changes of a subject resulting from a blast. In particular, the present invention relates to an ingestible capsule, which when swallowed and passed through the subject, can be used to capture, record and transfer information including internal blast pressures experienced by the subject.

Abstract: A microneedle system includes an ingestible structure and one or more microneedle units secured to a surface of the structure. Each microneedle unit has a plurality of barb members extending from the outer surface of a microneedle. The microneedle unit is secured to the structure by a displacement member, which displaces the microneedle unit when in a released state. The displacement member may be held in a compressed state by a dissolvable coating.
