"The phenomenon of electromagnetic emission (EME) from solids is based on the generation of electromagnetic field resulting from mechanical excitation of the solid in question. This phenomenon may be induced by external pressure, bending or shear stress,knock, friction, etc. When mechanical stress is applied to a solid, there arise cracks and a redistribution of electric charge takes place. The crack faces are charged with opposite charges thus forming a time variable electric dipole or an electricdouble-layer. Hence they become sources of an electromagnetic field, which may be detected in the vicinity of the solid in question by means of appropriate sensors. The main objective of this project consists in identifying the experimental detectionthreshold for the electromagnetic field generated by solids, to review and evaluate the devices available for picking up the basic parameters of thus generated field, by means of capacitance, inductance and other transducers.
