MICROFLUIDIC ANALYTICAL SYSTEM WITH POSITION ELECTRODES
First Claim
1. A microfluidic analytical system for monitoring an analyte in a liquid sample, the microfluidic analytical system comprising:
- an analysis module including at least one micro-channel for receiving and transporting a liquid sample;
at least one analyte sensor for measuring an analyte in the liquid sample, each of the at least one analyte sensors being in operative communication with a micro-channel; and
at least one position electrode, each of the at least one position electrodes in operative communication with at least one micro-channel; and
a meter configured for measuring an electrical characteristic of the at least one position electrode, the electrical characteristic being dependent on a position of the liquid sample in the micro-channel in operative communication with the at least one position electrode for which an electrical characteristic is measured.

Abstract
A microfluidic analytical system for monitoring an analyte (for example, glucose) in a liquid sample (e.g., ISF) includes an analysis module with at least one micro-channel for receiving and transporting a liquid sample, at least one analyte sensor for measuring an analyte in the liquid sample and at least one position electrode. The analyte sensor(s) and position electrode(s) are in operative communication with the micro-channel. The microfluidic system also includes a meter configured for measuring an electrical characteristic (such as impedance or resistance) of the position electrode(s). Moreover, the measured electrical characteristic is dependent on the position of the liquid sample in the micro-channel that is in operative communication with the position electrode for which an electrical characteristic is measured.
