Abstract
Nowadays, development of advanced devices or sensors often requires unique solutions that can be only solved with femtosecond laser micromachining. In this report we present the study of one of them: in order to create sensor for monitoring the health of metallic mould, conductive ceramic fiber (Fig. 1-a) has be integrated into pre-cut groove on the mould surface. Latter, the resistivity of the fiber has to be constantly monitored as it is directly linked to the wear level of the instrument [1]. Unfortunately, to get data about resistivity, electric wires should be attached to the ends of the ceramic fiber. This procedure is not straightforward: fiber has to be prepared in special way for sufficient and secure wire-to-fiber contact after the soldering. This preparation consists of creating micrometric notch in the fiber (Fig. 1-b) for precise wire positioning and tight attachment.
