Abstract

A screen-printed electrode (SPE), intended to be used as part of a cardiac mapping system, was fabricated and evaluated to determine if SPEs are a suitable alternative to current electrodes. The SPEs were designed in AutoCAD and screen-printed using silver conductor ink and an insulating paste. Measurements were taken during electrode development to determine how well the design translated to the final printed product. The efficacy of the insulating material used, and the affects of print speed on print quality were also evaluated. Finally, the performance of the SPEs was studied through a stimulating and recording model, as well as electrochemical analysis. The electrochemical analysis inluded modifying the silver electrode to produce a silver, silver chloride electrode. The results showed promise and provided insight on where efforts should be focused to advance the development of SPEs. Overall it was concluded that SPEs would be well-suited for mapping cardiac electrical activity.
