ORGANIC ELECTROCHEMICAL SENSOR FOR MEASURING BODY PARAMETERS

摘要

The present invention relates to an OECT sensor (1) for determining biochemical parameters in a subject's perspiration, comprising a filament (2) coated with a first layer (3) made of a conductive polymer, wherein the ends of the filament (2) are connected to two electrodes (4, 4′), wherein a first electrode (4) is grounded (V0), while a negative potential (V−) is applied to the second electrode (4′), the sensor (1) further comprising a control electrode (5), to which a positive potential (V+) is applied, wherein the filament (2) comprises a second layer (6) comprising an enzyme which catalyzes a transformation reaction of an analyte present in the liquid to be analyzed with generation of cations.

1. An organic electrochemical sensor (1) for determining biochemical parameters in a liquid to be analyzed, comprising a filament (2) coated with a first layer (3) made of a conductive polymer, wherein the ends of the filament (2) are connected to two electrodes (4, 4′), wherein a first electrode (4) is grounded (V0), while a negative potential (V−) is applied to the second electrode (4′), the sensor (1) further comprising a control electrode (5), to which a positive potential (V+) is applied, the control electrode (5) being positioned with respect to the filament (2) so that the two ends of the filament form the “drain” and “source” of a transistor, while the control electrode (5) forms the “gate” of the transistor when a drop (G) of the liquid to be analyzed is simultaneously put into contact with the filament (2) and the control electrode (5), characterized in that the filament (2) comprises a second layer (6) comprising an enzyme which catalyzes a transformation reaction of an analyte present in the liquid to be analyzed with generation of cations.
