  1. Prototype Presentation Stephanie Moran, Ryan Rosario, Zachary Stauber, Bethany Tomerlin, Juan Carlos Ybarra

  2. We modified our goals to more suitably match our application Inexpensive High Elongation (>10%) Fast Response Time Precision

  3. Current Improved Processing Setup Weighing Carbon Black Increased Mixing Time Using Katjen Carbon Black Increased Surface area: 1400 m2/g Typical Carbon Black is 100-500 m2/g

  4. Future Improvements to Processing Moving to a Silcone Rubber - 20:1 Mixing Ratio -Increase mixing Time Purchasing A Dispersion Blade Placing Samples Under Hot Press to Cure

  5. Four-point resistance measurements eliminate errors due to changing contact resistance.

  6. An automatic data acquisition setup allows for a faster sample rate. Strain vs. Time Voltage Output Multimeter Multimeter Resistance Output

  7. Sensor Arrangement and Data Processing Final Design: • Output: • Resistance vs. Strain • Position of sensor Bread Board Arduino Multiplexer Amp MC

  8. Requirements for Final Design • Glove Requirements: • Flexible • Relatively rigid substrate for strain measurement • Sensor Requirements: • Thinner • More elastic at higher strain rates • Possible Solutions: • Integrating sensor into fabric of glove • Create a glove with selective rigid sections • Molds with depth much smaller than those being used • Cut samples with proper shape.
