  1. Electro-Active Polymers By: Isaac Garza MEEN 3344

  2. What are Electro-Active Polymers? • First discovery were in 1880 by Wilhelm Röntgen • Two types of electro-active polymers • Natural • Artificial • A lightweight strip of highly flexible plastic that bends and functions similarly to a human finger when an electrical voltage is applied to it.

  3. How are they Used? • Small Robotic Devices • Artificial Muscles

  4. Dry Polymers Electrostrictive, Electrostatic, Piezoelectric, Ferroelectric Require high activation voltage (>100 V/µm) They can also be made to hold DC voltage which would allow robotic applications They also have a greater mechanical energy density Wet Polymers Ion exchange, conductive polymers, gels Only a 1-2 drive voltage is required There is a need to maintain their wetness It is difficult to sustain DC-sustained displacements Two Categories of EAP

  5. Dry Polymers Electrostrictive graft elastomers, electrostrictive paper, electro-viscoelastic elastomers, liquid crystal elastomer materials Wet Polymers Carbon nanotubes, conductive polymers, electrorheological fluids, ionic polymer gels EAP Materials
