The present invention relates to a device for sensing a target chemical. The device includes a flexible, non-planar substrate; a printed, solid-state sensing element comprising a chemical sensing material which produces an electrical signal upon interaction with the target chemical; a first printed electrode comprising a first conductive composition; and a second electrode comprising a second conductive composition. The first and second electrodes are electrically isolated from one another, and one or both of the first and second electrodes is in electrical contact with said sensing element. The first and second electrodes and the sensing element collectively form an electrochemical sensor which is coupled to the flexible, non-planar substrate. Medical devices comprising the device of the present invention and methods of making a device for sensing a target chemical are also disclosed. |
