Highly conductive woven fabrics (WF) can be used as electronic components. Resistivity is an intrinsic physical property of the conductive textile materials (CTM). The McLachlan model that describes the resistivity of a two-component macroscopic composite (TCMC) subjected to a constant external electric field was proposed to predict the resistivity of fabrics. The volume fraction of voids in material, the voids dimension, and a single morphology parameter were taken into account. The resistivity of a chosen WF was determined based on the model. Verification of the received results was carried out. In the case of four samples, the verification was confirmed by the high level of prediction being in the range of 83-88%. In the case of one sample, the verification was negative (26%). This allowed one to pay attention to the influence of compactness and irregularity of the woven structure on results received using the model.

“…In this case, conductive yarns are used during sewing, embroidering, or weaving. 7,8 Moreover, conductive fabrics can be enabled using coating techniques such as printing, sputtering, electroless plating, and vapor coating. 6,[9][10][11] Resistivity is an intrinsic physical property of the CTM.…”

“…In previous studies, it was mainly the electronic functionality of electronic textile that has been investigated (Edmison et al, 2002;Dalton et al, 2003;Marlescu et al, 2003;Bonderover & Wagner, 2004;Coosemans et al, 2006;De Rossi, 2007;Nakad et al, 2007;Zysset et al, 2010). In the study of Bonderover & Wagner (2004) the electrical signal from an inverter woven in a fabric was assessed and the efficiency of cluster computing in an electronic textile was tested by Marlescu et al (2003).…”

QC methodologies are mainly used to reduce the computational costs of conservative atomistic lattice computations. Recently, a virtual-power-based variant has been proposed that enables its use for non-conservative lattice computations. In this contribution the virtual-power-based QC approach is adopted in combination with a recently proposed mesostructural lattice model for electronic textile in order to investigate its mechanical behaviour. The interactions of the lattice model for electronic textile are modelled elasto-plastically and hence, regular conservative QC approaches are not adequate. This article incorporates a modification of a previously defined exact summation rule for QC methods -by sampling the lattice interactions directly instead of via the lattice nodeswhich leads to a significant reduction of the computational cost, whereas the accuracy of the summation rule remains unaffected. The presented methodology is used to efficiently investigate the failure envelope of an electronic textile -a woven fabric with embedded electronic components and conduc- tive wires -and the dependence of the failure envelope on the locations of the conductive wires and the stiffness of the weft yarns is investigated as well.

“…Nakad et al designed an electronic acoustic array in order to detect the location of passing vehicle according to vehicle's acoustic emissions. This acoustic array efabric was developed by first weaving of conductive yarns and then by integration of microphones to certain location of fabric [21]. Moreover, there are some other studies focusing on electromagnetic shielding effect of woven e-fabrics.…”

A combined two-staged analytical hierarchy process (AHP) was proposed with respect to its compatibility in selection of e-textile architecture. Specifically, it was examined in its ability to support decision in determination of appropriate e-textile structures prior to sensor integration. The e-textile structure selection methodology for sensor integration was implemented by interviewing with the experts from the fields of textiles and electronics; hence, it was constructed as two-staged methodology including both experimental study and AHP. In this respect, different e-textile structures including transmission lines containing 15 different conductive yarn types with three different weave types were manufactured via weaving technology in the first stage as experimental part of the methodology, and then, in the second stage, the alternatives based on experimental study were evaluated using AHP. The comparisons were made using priority scales assigned by expert team and synthesized to get aggregated global ratings. In conclusion, appropriate e-textile structures based on weaving manufacturing technology for sensor integration were chosen using AHP technique by ranking alternatives.
