Method and composition for moisture ingress protection, and electronic device comprising same

An electronic device comprising:

• a first layer including an upper conductive element;
• a second layer including a lower conductive element facing the upper conductive element;
• a spacer positioned between the first layer and the second layer, with the first layer, the second layer, and the spacer collectively defining a sensing chamber;
• and
• an electrically non-conductive thixotropic liquid within the sensing chamber;
• wherein, in use, the first layer and the second layer are configured to move toward and away from each other within the sensing chamber to vary the resistance of the electronic device, and
• wherein movement of the first layer and the second layer toward each other displaces the thixotropic liquid from an initial state coating at least one of the upper conductive element and the lower conductive element to permit contact between the upper conductive element and the lower conductive element, and movement of the first layer and the second layer away from each other returns the thixotropic liquid to the initial state.
