Method for detecting the detachment of a bandage, bandage suitable for implementing the method, sensor array and shielding to reduce capacitive coupling from the vizinhan\u00c7as environmental to the electrodes of the patch.The present invention is a method to detect the curative and detachment from the dressing, which is applied to a surface of an object at least partially electrically conductive. The dressing includes an adhesive for affixing the bandage to the object electrically conductive and at least two electrodes arranged at a distance to the object is electrically conductive.A voltage is applied to the first and second electrode establishing an electrical circuit comprising a first capacitor between the first electrode and the electrically conductive object and a second capacitor between the second electrode and the electrically conductive object.The changes of capacitance between at least one of the first and second electrode and the electrically conductive object are detected, and an alarm is activated when the changes of the capacitance reaches a predetermined value. This advantageously provides a method by which a leak can be detected quickly.
