A method and apparatus of detecting incipient corrosion on surfaces of an object. The method comprising immersing the object into an electrolyte, and detecting by electrochemical techniques the presence of corrosion on the surfaces of the object based on current originating from redox reaction of iron.

Method and apparatus for detecting corrosion

According to an example aspect of the present invention, there is provided method for measuring wound healing, comprising, measuring a wound impedance by a first tetrapolar arrangement of electrodes arranged on both sides of a wound, measuring a reference impedance by a second tetrapolar arrangement of electrodes arranged on one side of the wound, determining, by a controller, wound healing on the basis of the wound impedance and the reference impedance measured over a frequency range.

Measuring wound healing

The present invention relates to the field of electrotherapy and measuring by means of electric cur-rents for diagnostic purposes, and more particularly to an electrode arrangement for facilitating wound healing, a method for measuring wound healing and a wound dressing having an electrode arrangement. A wound dressing according is described which includes at least two impedance reference electrodes, a frame like counter-electrode and stimulation electrodes in a form of an array; and a bioadhesive affinity layer surrounding the stimulation electrodes; said wound dressing being suited for applying on top of the wound so that the stimulation electrode array is on the wound area, and that the at least two impedance reference electrodes and the frame like counter-electrode are suited for placing in contact with the healthy skin surrounding the wound area; which electrodes, are suited for applying LIDC type electrical stimulation current to the wound area and for bioimpedance measurement.
