Abstract: A gradient sensing probe system, and method of using same, including a sensing segment which includes a plurality of sensors, a support structure, and an electrical interface having first and second faces. The system further includes a housing, a power source, and an electronics package including a controller and disposed within the housing. The sensing segment is configured to measure external gradients and to exchange data with the controller. The power source is connected energetically to provide power to the sensing segment and the electronics package, and is controlled by the controller.

Abstract: A system and method is disclosed for obtaining measurements of the electric fields around skin wounds and lesions on mammals noninvasively. The system and method is comprised of a vibrating metallic probe tip that is placed close to the skin in the air. By applying a series of known voltages to the metal probe tip or to the skin beneath it, the skin's local surface potential can be measured and the lateral electric field can be calculated from the spatial distribution of surface potential measurements. Surface artifacts that can affect the measurements are removed and active feedback is used to maintain a constant distance between the probe and the skin surface.

Abstract: A polarographic self-referencing probe uses an electrode that is oscillated between two positions. Depending on the electrode used and the voltage applied, the probe can be used to measure oxygen, nitric oxide, or other molecules or compounds.
