1. A biosensor, comprising:
- an electrically or electronically insulating support (2), comprising at least one useful face (20), a multiplicity of electrically or electronically conducting electrodes (31, 32) that are placed on the useful face (2a) of the support in any predetermined operating arrangement, and are exposed in the sense that said electrodes may be brought together into contact with one and the same external medium, for example liquid, a plurality of ligands each multiply attached to respectively different electrodes (31, 32), a multiplicity of electrical terminals (4), corresponding to said electrodes (31) respectively, which are placed on a useful face (2a or 2b) of the support (2) and are exposed in the sense that said terminals may be electrically or electronically connected to the outside independently of one another, a multiplicity of electrically or electronically conducting tracks (5), each running along one (2a) of the faces of the support (2) and/or the other (2b), connecting the multiplicity of electrodes (31 and 32) to the multiplicity of terminals (4) respectively, and a layer (6) of an electrically or electronically insulating material coating one (2a) face of the support (2) and/or the other (2b), on the one hand at least partly covering said tracks (5)- and on the other hand exposing both the electrodes (31, 32) and the terminals (5), characterized in that, in combination, on the one hand the multiplicity of electrodes (4) is placed in an extreme zone (1a) on the opposite side from another extreme zone in which the electrical terminals (5) are grouped together, and on the other hand the support (2) includes at least one flexible zone (1c) located between the two extreme zones.

Abstract
The invention concerns a sensor (1), in particular a biosensor, comprising an electrically or electronically insulating support (2), including at least one active surface (20), a plurality of electrically or electronically conductive electrodes (31,32), arranged on the active surface (2a) of the support in a predetermined operative arrangement, exposed, that is said electrodes can be jointly placed in contact with a common external medium, for example a liquid medium; a plurality of electric terminals (4) respectively corresponding to said electrodes (4), arranged on the active surface (2a, 2b) of the support, exposed, that is said terminals can be electrically or electronically connected outside, independently of one another; a plurality of electrically or electronically conductive strips (5), extending along one (2a) and/or the other (2d) of the support surfaces, connecting the plurality of electrodes (31,32) respectively to the plurality of terminals (4); an electrically or electronically insulating material layer (6), coating one (2a) and/or the other (2b) of the support surfaces, covering at least part of said strip conductors and exposing both the electrodes (31,32) and the terminals (5). The invention is characterized in that, in combination, the plurality of electrodes (4) is arranged in an end zone (1a) opposite another end zone wherein electric terminals (5) are assembled together and the support (2) comprises at least one flexible zone (1c), located between the two end zones.
