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

9Requirements for Final Design
Glove Requirements:• Flexible• Relatively rigid substrate for strain
measurement
MC
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.
Sensor Requirements:• Thinner• More elastic at higher strain rates
