Abstract

Impedance spectroscopy methodology is used in this article to evaluate the influence of axial applied stress on complex impedance components of as cast CoFeBSi wires in the 100 Hz to 300 kHz frequency range, at 10 mA ac current. Based on the obtained results, problems of practical significance are discussed since the envisaged application is the construction of sensitive stress sensors for detection of such as pressure, tension and stream speed for liquid and gases.
