In situ tensile tests in a scanning electron microscope (SEM)were conducted for PPy-coated electrically conducting yarns, which were prepared by the same procedure as that for the PPy-coated fabrics, enabling it possible to observe in situ the phenomena that occurred on the fiber surface during fabric deformation. The investigation revealed that the PPycoated nylon/polyurethane fabrics exhibited a high strain sensitivity of over 400 and very large workable strain range greater than 50 UR - https://drive.google.com/file/d/1vWWB9lDfI17ztehVqE4A7YqTIP9cBH3X/view?usp=drivesdk ER -
