This allows for the detection of initiation and growth as well as for the localization of damage in mechanically loaded materials.
If materials are mechanically loaded, elastic energy is produced and stored within the material [2].

At present, the best electrode is either platinum or platinum-based materials.
However the cost of the use of these materials is too high and the anode surface poisoning by CO-like intermediates to loss of activity[4-6].
Concerted research work has been carried out to search for the catalytic activity of cheap metals and composite materials.

Use the standard resistance instead of the impedance of the materials.
But different materials have different characteristics, the difference of the temperature - impedance curve can be large.

Introduction The machining characteristics of engineering materials depend primarily on their mechanical and chemical properties.
Such properties depend on the machining process and the engineering materials used in production.
Therefore, cutting velocities should be limited by the fracture toughness of tool materials in high temperatures.

Two different samples were prepared: first a Ba2Ti9O20 specimen and second a 1wt% Nb2O5-added Ba2Ti9O20 composition, using BaO and TiO2 as precursor materials.
Raw materials used were barium carbonate (BaCO3) and titanium oxide (TiO2).
