Verification of Surface Conductance Model of Textile Materials

Abstract

Surface conductance is one of the main parameters which describes basic characteristics of specific textile materials. These textile materials are used, for example, in environments with higher requirements on hardware electrostatic protection during their production process. Published measurement standardized methods are followed by modeling methods which do not reach satisfactory results. This paper is therefore focused on the modeling of surface conductance of textile materials. The results show that the structure of textile materials can be seen as serial-parallel connections of resistors. A derivation of this model is described.

Monometallic Textile Electrodes for “Green” Batteries

“…Tin anodes are not covered with the standard yellow and green layer indicating the anode polarization. Under the operating conditions described above these would turn dark grey and tin would be released to the bath in the form of divalent ions, resulting in a tough coating with a higher surface area compared to conventional decorative gloss paints based on tetravalent ions [4]. The main reason for this is the smaller surface area of the anode compared to the cathode.…”

“…With a proper conductive structure, i.e. if the desired electrical conductivity is obtained, such materials ensure protection against ESD (electrostatic discharge) [4]. Recent years have witnessed advances in increasing the electrical conductivity of materials while the application focus shifted to the implementation of flexible electrically conductive elements or electromagnetic shielding [5].…”

RFID Textile Antenna and Its Development

“…The textile material can be modelled as finite grid of resistors. However, it assumes only woven fabric [11]. The example is depicted in Figure 10.…”

“…Here, chip sensitivity is -10 dBm and the maximum radiated power by the reader is 3.2 W EIRP. Thus from the formula the transmission power coefficient for TAG1 and TAG2 is equal to, τ 1 = 0.97 (10) τ 2 = 0.87 (11) Thus the maximum range obtained is d max = 2 m for TAG1 and d max = 1.2 m for TAG2.…”

Dry Wearable Textile Electrodes for Portable Electrical Impedance Tomography

“…Additionally, the electrically conductive textile materials have been developed in various types of clothing for health care. Some properties of textile material are preferred for the realization of these electrodes to provide high comfort for the users while ensuring good quality of measurements, including sufficiently high conductivity, cotton-based fabric, fixed part of the clothes, and standard maintenance (washing and ironing) [ 24 , 25 ]. Therefore, some studies have proposed textile electrodes for electrocardiogram (ECG) measurement devices with high comfort for the users [ 26 , 27 , 28 , 29 ].…”
