Ceramics are usually electrical insulators although some exhibit semiconducting and conducting behavior also. The defining property for a material to be used as an electrode is that it be conductive. The laws governing conduction of heat are very similar to Ohm's Law, which governs electrical conduction. SMPs can retain two or sometimes three shapes, and the transition between those is often induced by temperature change. 1.
