摘要： A method of detecting a leak between a dressing and an at least partly electrically conductive object, such as the skin of a patient, said method includes providing, in the dressing, a first and a second electrode separated from the patient by an adhesive that attaches the dressing to the patient. The method includes applying a signal to an electrical circuit that includes the first and second electrode, and detecting changes in an electrical quantity of the first and second electrode based on frequency responses of the electrical circuit to the signal. The method additionally includes activating an alarm based upon detecting the changes in the electrical quantity of the electrical circuit.
