Apparatus and methods for transdermal sensing of analytes in interstitial fluid and associated data transmission systems
First Claim
1. An apparatus for testing interstitial fluid in a subject comprising a disposable integrated micro-sensing unit and a reusable applicator,wherein the micro-sensing unit comprises a plurality of hollow transdermal microneedles, a microfluidics chamber, one or more sensors capable of detecting the presence or concentration of one or more analytes, a reference electrode, a pH sensor, a temperature sensor, electronic circuitry to control the testing, a casing, a spacer, a vent, and electrical contacts;
- and wherein the micro-sensing unit is configured to transmit data that result from the testing to a receiver.
