    摘要： A planar interdigitated dielectric sensor useful for measuring the surface properties of a material is disclosed. The sensor is formed on an insulating substrate. Attached to the surface of the substrate is an excitation and response electrode disposed in an interdigitated pectinate configuration. Filling the space between the electrodes is an insulating material of known dielectric properties. The upper surface of the electrodes are generally coplanar with respect to the insulating material between the electrodes thus forming a flat upper surface on the sensor. This flat upper surface serves to eliminate air gaps between the sensor surface and sample when analyzing relatively viscous materials.
