<p>The present invention relates generally to the field of measuring glucose levels in a body fluid of a subject, in particular to non-invasive measuring of blood glucose in blood of a subject. A device is disclosed comprising an electrically conducting probe comprising a plurality of electrodes adapted for measuring electrical impedance of the tissue of a subject, typically skin, a sensing device adapted for sensing at least one concentration of an ion in the tissue, typically acidity (pH), wherein said electrically conducting probe and said sensing device are adapted to obtain said electrical impedance of the tissue and said concentration of an ion in the tissue simultaneously. The device further comprises a blood glucose determining unit adapted for determining an estimate, typically a concentration, of blood glucose based on said electrical impedance of the tissue and said concentration of an ion in the tissue. Further, a device is disclosed comprising an electrically conducting probe comprising a plurality of electrodes adapted for measuring electrical impedance of the tissue of a subject, typically the skin, wherein at least one of said plurality of electrodes is adapted to, when being in voltage mode, sense a signal representative of a concentration of an ion in the tissue, typically acidity (pH), wherein said electrically conducting probe is adapted to simultaneously obtain said impedance of the tissue and said concentration of an ion in the tissue, the device also comprising a blood glucose determining unit adapted for determining an estimate, typically a concentration, of blood glucose based on said electrical impedance of the tissue and said concentration of an ion in the tissue. Furthermore, methods for non-invasive determination of an estimate of blood glucose in blood of a subject are disclosed.</p> |
