Novel temperature sensors based on strain-relieved braiding constructions

Novel textile temperature sensors based on strain-relieved braiding constructions offer attractive monitoring possibilities for numerous application fields involving e-textiles in general, and medical textiles in particular. Thus, the research work presented in this paper focused on theoretical foundations, manufacturing, and procedural, mechanical as well as thermal testing of these newly developed, textile-based sensors for temperature measurements. The median basic resistance of the scalable sensor yarns using a helical stainless steel wire is about 0.81 omega/mm. Within the temperature range of 22 to 40celcius, the developed sensor yarn has a mean linearity deviation of 0.028 K. The measured temperature coefficient is 0.68 x 10(-3) K-1, which correlates with the properties of the stainless steel wire.
