Softgoods Webbing Integrated Strain Sensor for Inflatable

This SBIR project focuses on design, fabrication, and testing of textile based strain sensors to measure the health of structural softgoods elements.nbsp;nbsp; In Phase I Paragon iterated through dozens of sensor configurations and down-selected to a single embroidered configuration with exceptional linear and cyclical trends.nbsp; The Phase II effort will include further iteration of the down-selected design configuration to optimize for repeatability and manufacturability.nbsp; Iteration and testing will utilize a dead-weight system to inform further configurations and include long duration testing of at least 1 month.nbsp; Phase II will integrate conductive traces directly into the webbing to minimize wiring needed across a structure.nbsp; The SWISS Phase II effort will develop a software and electronics interface to multiplex an array of sensors, giving simple usable data output.nbsp; Paragon will design and build a subscale inflatable test article, deploy the SWISS sensors on the article, and test/evaluate the system in a relevant environment of plain-woven restraint lines under constant load over a multi-week evaluation.nbsp; The culminating test will utilize optical tracking to evaluate the sensor performance.nbsp; Deliverables will include the actual test article for NASA evaluation and a single-strand sensor, as well as the detailed reports therein.
