    摘要： The present invention is directed to a sensing element that comprises a flexible substrate having first and second opposite surfaces; at least one sensor disposed on the first surface of the flexible substrate; an adhesive layer substantially covering the second surface of the flexible substrate; and a release liner releasably adhered to the adhesive layer so that upon removal of the release liner the adhesive layer is exposed for securing the sensing element to the catheter. The release liner permits the sensing element to be positioned at a desired location within the catheter after which the release liner can be removed to expose the adhesive layer. The adhesive layer can then be used to attach and secure the sensing element at a desired location on the catheter. As a result, the need for additional adhesives can be reduced or eliminated.

    摘要： A flux limiting layer for an intravenous amperometric biosensor is formed on a substrate to limit a diffusion rate of an analyte from blood to an enzyme electrode. The layer may be formed from ethylene vinylacetate (EVA) dissolved in a solvent such as paraxylene, spray-coated to cover a portion of the electrode, and cured to seal the electrode to the substrate. In a glucose sensor having glucose oxidase disposed on the electrode, thickness and concentration of the EVA layer are optimized to promote a linear output of electrode current as a function of blood glucose concentration.

    摘要： A method of creating a sensor that may include applying a first conductive material on a first portion of a substrate (110) to form a reference electrode (125) and depositing a first mask (130) over the substrate, the first mask (130) having an opening that exposes the reference electrode and a second portion of the substrate. The method may also include depositing a second conductive material (140) into the opening in the first mask, the second conductive material (140) being in direct contact with the reference electrode (125) and depositing a second mask (150) over the second conductive material, the second mask having an opening (160) over the second portion of the substrate, the opening exposing a portion of the second conductive material, which forms a working surface to receive a fluid of interest. The sensor is also described.
