Wires from the silicon chip connected each electrode to a plug sitting on top of his head, and a cable attached to this plug transferred data from the wires to a computer for analysis.

The stress inspection of steel cable, and the judgment and analysis of health status of steel cable is an unresolved but desiderated problem in engineering field.

The experimental data and analysis results provide a technologic basis to design VIM of the underwater cable in towed array sonar.
