  • Patent number: 11361885
    Abstract: A method includes coating at least one conductive element of an electronic device with an electrically non-conductive thixotropic liquid. An electronic device includes a first layer including an upper conductive element, a second layer including a lower conductive element, and a spacer positioned between the layers. The first layer, the second layer, and the spacer define a sensing chamber in which the upper and lower conductive elements move to vary the resistance of the electronic device. A non-conductive thixotropic liquid is present within the sensing chamber. Movement of the layers toward each other displaces the thixotropic liquid from an initial state coating at least one of the conductive elements to permit contact between the conductive elements, and movement of the first layer and the second layer away from each other returns the thixotropic liquid to the initial state.
