  • Publication number: 20110284374
    Abstract: An electrochemical sensor is described, containing a sensor substrate and at least one set of electrodes comprising a working electrode, a reference electrode and optionally an auxiliary electrode, further containing at least one reaction vessel, which is tightly connected to the sensor substrate and inside which is located at least one working electrode, whereas at least a part of the sensor substrate forms a vessel bottom. The vessel can contain a lid and also other preferred embodiments are described. The invention further describes a method of manufacture of the electrochemical sensor with the integrated reaction vessel, particularly by injection moulding.

  • Patent number: 7811431
    Abstract: A nanostructured working electrode of an electrochemical sensor wherein the working electrode is composed of a material in the form of a film and is inserted onto the sensor. The electrode can be prepared from materials the use of which was impossible in the working electrodes known in the art (e.g. metals of defined purity). A method of manufacturing of the nanostructured working electrode and an electrochemical sensor containing the nanostructured electrode is disclosed.

  • Publication number: 20100181211
    Abstract: The invention relates to an electrochemical sensor or biosensor that contains a substrate which bears at least one working electrode and a heating element, optionally also a temperature measuring element. This electrochemical sensor or biosensor allows to achieve better mass transport towards the working electrode during the measurement process. The invention further relates to a method of electrochemical measurement using the sensor or biosensor of the invention.

  • Publication number: 20050204939
    Abstract: Object of the present invention are components with three dimensional structure prepared by thick film technology by print, where between the printed layers is inserted at least one membrane. The membrane is according to the present to invention at least in a part of the final product. The membrane can be provided with holes which are necessary for next technological steps. The inserted membranes can have pores of the size of 50˜tm to 10 nm and a thickness of 1 to 200˜tm. Method of producing of components with three-dimensional structure by thick film printing technology according to the invention lies in that between some of the printed layers is inserted a suitable membrane, which allows to lay on next layers without influence to previous layers. The printing can be done by screen-printing.
