Sensor to detect the intrusion of moisture

<body><p align="left"><font face="AvantGarde Md BT" color="#800000"><b><i>In-Situ</i> Sensor to Detect Moisture Intrusion and Degradation of Coatings, Composites, and Adhesive Bonds</b></font></p><p>An <i>in-situ</i> sensor, based on electrochemical impedance spectroscopy (EIS), has been developed that can detect the absorption of moisture in polymeric systems. In the case of a coated metal, moisture intrusion into the coating foretells corrosion of the substrate so that the sensor is sensitive to the very early stages of corrosion. In an adhesive bond, the sensor monitors ingress of moisture into the bondline that causes plasticization of the adhesive and hydration of an aluminum adherend ... and much more!!</p><p>If you are viewing this text, your browser lacks the ability to read frames.
