Abstract
A device for the measurement of electrical properties on a surface. Sensor consists of several conductive elements arranged at vertices of a three-dimensional geometry. As such, the device achieves a favorable sensing configuration regardless of initial orientation. The device includes circuitry for interfacing with the conductive elements. This circuitry determines the electrical properties of the surface. The measurement has many uses, one of which is to discriminate between dry and wet surfaces. This patent presents various analysis methods to determine the electrical property.

A device for measuring electrical properties on a planar surface without a preferred orientation, the device comprising:
- A probe, for resting on the planar surface to detect electrical properties;
- Four or more vertices formed in the probe, between which a three-dimensional geometry is formed, for contacting the planar surface;
- Two or more electrically conductive terminals formed at vertices on each face of the three-dimensional geometry, for providing a conductive path to the planar surface;
- and
- Circuitry for interfacing with the electrically conductive terminals for determining electrical properties of the planar surface;
A method of measuring electrical properties on a planar surface without a preferred orientation comprising:
- placing a probe with four or more vertices, between which a three-dimensional geometry is formed and, for each face, at least two vertices are electrically conductive, on the planar surface;
- providing the electrically conductive vertices with an electrical stimulus;
- measuring the electrical response;
- and
- determining an electrical property of the gap between the electrically conductive vertices on the measured response.
