Conformal Conductivity Probe

ABSTRACT: PaneraTech is proposing a conformal conductivity probe that utilizes a very innovative resonant-based approach to accurately and quickly measure the conductivity of curved aircraft surfaces and gap fillers. The proposed sensor is designed to allow for a very fast non-destructive, in-situ evaluation of the electrical conductivity in the range from 0 to 10 ohms/square. Preliminary studies have already shown that the probe interacts strongly with the conductive surface in a very small sensing area and is also very sensitive to these conductivities. During Phase I, we will optimize the sensitivity and sensing area of our innovative non-contact resonant-based sensor, which will operate in the 8-18 GHz band. BENEFIT: The proposed conformal conductivity probe offers a number of significant benefits to U.S. Air Force by ensuring expected electrical conductivities of conductive surfaces and gap fillers are achieved on the platform. This tool will allow for a very fast, in-situ measurement leading to decreased downtime of the aircraft. Rapid and high resolution conductivity measurement results obtained by the probe will allow for fast and effective action to qualify or repair sealants, gap fillers and surfaces, which will lead to reduction of the platform"s unavailability and extension of its life span. Beyond military applications there are also other industries that employ continuous and curved conductive coatings that can be tested by utilizing this tool including automotive, marine, construction and manufacturing applications.
