Prototype Presentation

Stephanie Moran, Ryan Rosario, Zachary Stauber, Bethany Tomerlin, Juan Carlos Ybarra

slide2

We modified our goals to more suitably match our application

Inexpensive

High Elongation (>10%)

Fast Response Time

Precision

slide4

Improvements to be Made to Our System in Order to compete with existing Motion Capture Technologies

  • We need:
    • Movement through Space
    • Rotation
    • Real Time Feedback

Can act as a supplement

    • Reduce Errors
slide5

Our Product Could Be Used to Monitor and Provide Feedback for Joint Extension

  • Inexpensive
  • Output of strain
  • Track degenerative diseases
  • Posture Feed Back Loops
  • Need to reduce distractibility
slide10

Bubbles Create Stress Concentrators In Rubber

Improvements in Processing to Help Consistency

Weighing Carbon Black

Alternating Mixing Time

slide19

Minimum Goals for Strain Sensor Prototype

Minimum Requirements:

Sensor

MC

Text Output:

Strain vs. Resistance

R = 453.9 ε 3 - 198.7 ε 2 + 95.23 ε + 5.597

slide20

Glove for Final Design

Final Design:

  • Output:
  • Resistance vs. Strain
  • Position of sensor

Bread Board

Arduino

Multiplexer

Amp

MC

slide21

We plan on altering our current process to yield more reproducible samples

Better dispersed phase

Optimize void removal

slide23

Conduction in the composite cannot be explained by tunneling, but can be modeled by Mean Field Theory.
