Knitted Strain Sensor Material and Structural Enhancement
Enhancing Monocopter Directional Movement Through Mid-Flight Wing Shape Manipulation
Due to limited time and resources, I utilized the CTE difference of PET and UHMWPE as a base to examine material behavior in the three different knit structures above. These learnings would inform more strategic material choices and knit structures later.
Hypothesis 1 Data + Results
I encountered challenges in sourcing the right nitinol wire and determining the most effective method to heat-set specific shapes. Initially, I attempted to dremel refractory bricks into my desired airfoil-inspired form, but the mold could not withstand the wire's strong force. As a result, I had to innovate and repurpose existing lab tools, as seen in section 2, to achieve the desired shape.
After successfully heat setting my nitinol wire, I tested the wire's ability to return to its heat set shape once exposed to a heat stimulus (in this case, warm water).
