In order to address infant respiratory distress syndrome, this study attempts to develop and characterize a textile strain gauge fabricated with stainless steel, wool, elastic, and tencel. Faire Isle knitted patterns are investigated in order to create channels of conductivity for a linear sensor. The effect linear yarn density on linearity and sensitivity and hysteresis of the sensors is also investigated for sensor optimization. It was found that there was a significant difference between the patterned and non-patterned samples. The patterned sensors were found to have a lower range of resistance than the non-patterned sensors and a smaller average standard of deviation between measurements. The 7 tension, lower linear yarn density, elastic patterned sample was the only sample to not exhibit hysteresis after three trials as well as have a linear range from 11.5cm to 13cm where the sensor behaves in accordance with a linear transfer function.
