Abstract
A probe sensor has a printed circuit comprising a coplanar transmission line, a ground plane, a plated-through contact via, and a part-circular ring of ground vias surrounding the contact via. The coplanar transmission line and ground plane are formed on a first layer of the printed circuit, and the contact via and part-circular ring of ground vias are plated with a conductive biocompatible material on a second layer of the printed circuit. A system uses a network analyzer with the probe to measure electrical properties of biological tissue. Also described is a method of using the system to determine qualities of stored blood.
