Stitching Pattern

We used 180-degree phase change pattern like a cross-stitch pattern to avoid from a proximity effect. 

Poke the threaded needle through the corner of your paper. Sew upward in a straight stitch pattern of in and out, in and out along the flat part of the triangle. Leave several inches of thread on each end. 

Further, we examine the performance of TL samples embroidered with E-fibers of different thread densities. As depicted in Table 10.2, E-fiber TLs made of denser E-fibers clearly exhibited lower loss. That is, for TLs having the same stitching patterns, heavier fibers resulted in denser surface coverage (much like thicker carpets) and higher conductivity. We also observe that the loss for TL samples made by...

Simple electrodes may be engraved with patterns of stitching or other designs (including trade names, logotypes, etc.) and in the course of welding also emboss permanently the design in the area of the weld. 

Raschel Warp knit raschel fabrics are produced in a similar way as tricot fabrics except for their stitch motions. The motion results in elastic yams being put into raschel construction as lay-in-yams versus knit-in yams on tricot constractions as shown in Figure 3.7. This lay-in stmcture leads to the raschel fabrics with elastic stretch in the length direction. Other elastic bar movements are possible to increase stretch and modulus in width. Raschel machines can have up to 64 yam guide bars to produce fabric patterns as extensive as jacquard lace. Elastomeric fabrics made by raschel showed good elastic stretch, recovery, and modulus in both length and width directions as elastic yam lap increases. 

While these studies have shown that polyaniline- and polypyrrole-coated fabrics can behave as chemi-resistive sensors, it is also expected that similar chemi-resistive behavior will be achieved using ICP monofilaments and yams, which are woven or stitched into an existing fabric. Ultimately, vapor detection fabric will need to comprise of an array of sensors with the patterned response fed into a microprocessor in order to identify and determine the concentration of the vapor. The relatively low cost of production and subsequent processing of these electrically conductive fabrics provide the opportunity for designing a textile-based electronic nose, which possess built-in massive redundancy for the sensor array so that device will still function even if there is a localized break (rip, tear hole, etc.) in the fabric network. Specifically, in case some area of the sensor system fads, there is a massive redundancy in the garment such that other areas may stdl be able to acquire the information. This will greatly increase the rehabdity of the system.
