This paper describes the development, fabrication, packaging and mechanical characterization of a SiC based microprobe for myocardial ischemia monitoring during cardiac artificial arrest. The packaged microprobe has two SiC needles. One needle monitors the tissue impedance and the other controls the temperature. Both needles have been assembled on a ceramic substrate and packaged in epoxy resin. Mechanical characterization of the needles and the system as well have been performed. Yielding force measurements and insertion tests in heart tissue show that SiC-based needles have better mechanical properties than Si needles of the same length but with double the cross section area.
