Implantable self-calibrating biosensor Subcutaneously or intracorporeally implantable biosensor, characterized by a closed microfluidic circuit with calibrating fluids, which communicates by a backward micro-dialysis logic with the exterior of said circuit, an open and in contact with the tissues and the interstitial fluid working electrode, for its self-calibration. One or more working electrodes may be positioned inside openable boxes from EAP, and be opened for the duration of the measurement and closed immediately after, succeeding one another in the measurement, as their sensitivity is diminished.
