    Abstract: Composite airfoils of the present disclosure comprise a root section including a first surface. The airfoils comprise an intermediate section having a first surface and coupled with the root section at a first end. The airfoils comprise a tip section having a first surface and coupled at a first end with a second end of the intermediate section. The airfoils comprise a conductive material layer adjacent at least one of the first surface of the root section, the first surface of the intermediate section, and the first surface of the tip section. The conductive material comprises a first polymer, a second polymer, and a sulfonic acid.

    Abstract: A method (e.g., for characterizing a fluid) includes rotating an electrode assembly in a fluid at a rotation speed. The electrode assembly includes first and second electrodes. Rotation of the electrode assembly draws at least a portion of the fluid to move across the first and second electrodes. The method also includes measuring a potential difference between the first and second electrodes as the at least a portion of the fluid moves across the first and second electrodes due to rotation of the electrode assembly, and determining a streaming potential of the fluid using the potential difference.

    Abstract: The present disclosure provides a sensor system including one or more sensors having a first container fluidly coupled to a second container, the second container being configured to receive a conductive media from the first container. A first movable element is slidingly engaged with the first container to cause the second container to receive the conductive media from the first container. A first electrode is positioned in the first cavity and electrically coupled to the conductive media. In some examples, a second electrode is electrically coupled to the first electrode and the conductive media. The sensor deposits the conductive media on a working electrode to form an electrochemical cell and obtain one or more material properties of the working electrode. In some examples, the sensor system includes an array of sensors which deposit the conducive media in multiple locations on a working electrode to generate a material property map.
