Critical Function Prototype Development for Emergency Release Snowboard Bindings

This report outlines the progress and future focuses of our project aimed at developing innovative emergency release snowboard bindings. We detail key dates in our schedule, current project status, budget considerations, and insights into our critical function prototype (CFP) utilizing Shape Memory Alloy (SMA). Our findings confirm that SMA functions effectively in cold temperatures, essential for our design. We also share lessons learned, including operability and the simple circuitry involved. Our team is committed to finalizing designs and securing necessary funding as we approach the semester's end.
