Electrical Impedance Spectroscopy for Electro-Mechanical Characterization of Conductive Fabrics

Abstract: When we use a conductive fabric as a pressure sensor, it is necessary to quantitatively understand its electromechanical property related with the applied pressure. We investigated electromechanical properties of three different conductive fabrics using the electrical impedance spectroscopy (EIS). We found that their electrical impedance spectra depend not only on the electrical properties of the conductive yarns, but also on their weaving structures. When we apply a mechanical tension or compression, there oc… Show more

“…A number of RCMs were developed with parallel and series-parallel combinations by high-precision resistors (1% tolerance) and capacitors (1% tolerance). EIS studies were conducted with a QuadTech7600 (QuadTech Inc., USA) impedance analyzer [88] using the four-probe technique [89][90][91][92][93][94]. The EIS study was conducted with circuit combinations by injecting a 1 mA constant sinusoidal current at different frequencies and the impedances and phase angles were measured at 100 discrete frequency points within a frequency band of 10 Hz to 2 MHz.…”
