Abstract: The present disclosure is directed to a method for detecting a liquid on a main surface of a body. The method is performed through a detection device including a processing module, a reference electrode at a reference electric voltage and a first sensing electrode on the main surface and configurated to detect an environmental electric and/or electrostatic charge variation indicative of the presence of the liquid. The method includes the steps of: biasing the first sensing electrode to a bias electric voltage; while the first sensing electrode is at the bias electric voltage, acquiring a first charge variation signal indicative of the electric and/or electrostatic charge variation detected by the first sensing electrode; verifying whether the first charge variation signal is indicative of the presence of the liquid on the main surface, at the first sensing electrode; and, if it is, determining the presence of the liquid on the main surface at the first sensing electrode.
