Abstract

Screen printing is one of the best known and widely used techniques in printed electronics, with applications in biomedical devices. Several advantages of this technique include it’s robustness, versatility and good accuracy allow it to be used in the electronics industry. Advanced screen-printing machines require the specific selection of printing parameters, which have noticeable impact on the quality of printouts. In this paper, we present the results of squeegee firmness and screen density influence on the resistance of obtained printouts. The experiments were conducted using commercially available, thermally cured, conductive carbon and silver pastes which are commonly used to acquire conductive layers. Conductive traces of different lengths and widths were printed on an elastic polymer film. Printed samples were tested according to ANSI/AAMI EC12:2000/(R)2015 standard for disposable ECG electrodes.
