Abstract
A transducer cell array for electrochemical and electromechanical spectroscopy testing. The array has rows and columns of electrolytic volume cell elements that are spatially uniform. A reference electrode is common to all volume elements. Each counter electrode is individually addressable. The total impedance response provides a spatial image of the surface being tested.
Claims8
A transducer cell array for use in materials testing, comprising:
- a capillary array having a number of capillary elements open at each end, such that each capillary element has an open top end and an open bottom end;
- an electrically conductive reference electrode layer at the upper surface of said capillary array, said reference electrode layer extending down into a least a portion of each said capillary element thereby forming a reference electrode for each capillary element;
- a contact point array above the reference electrode layer, having a number of electrically conductive contact points, each of said contact points forming a counter electrode for a corresponding capillary element;
- and
- a contact grid having a number of electrical leads, one lead corresponding to each counter electrode such that each counter electrode is individually addressable.
