Barrett

Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.

Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

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.
