  • Method for manufacturing a sensor electrode
    Patent number: 5614246
    Abstract: In a method for manufacturing a working electrode for an implantable, electrochemical oxygen sensor a thin layer of a uniform mixture composed of an epoxy-based resin, a hardener and powdered vitreous carbon is applied onto a ring or hollow cylinder of biocompatible, inert, electrically conductive material, and the resin is hardened.

  • Method and apparatus for the electrochemical determination of oxygen concentration
    Patent number: 4853091
    Abstract: The electrochemical determination of the oxygen concentration, particularly in biological matter, is possible by means of an oxygen sensor with a measuring electrode and a counter electrode over long periods of time, even if the sensor is implanted, by taking the following measures; two potentials are cyclically impressed on the measuring electrode, with one potential (measuring potential) in the range -1.4 V.ltoreq..rho.Ag/AgCl.ltoreq.-0.4 V, and the other potential (recovery potential) in the range -0.2 V.ltoreq..rho.Ag/AgCl.ltoreq.+0.2 V; the dwelling time at the measuring potential is small as compared to the duration of the cycle; and the current flowing during the measuring period is evaluated as the measuring signal.
