Future Directions
The field of EAPs is far from mature, which leaves several issues that still need to be worked on. The performance and long-term stability of the EAP should be improved by designing a water impermeable surface. This will prevent the evaporation of water contained in the EAP, and also reduce the potential loss of the positive counter ions when the EAP is operating submerged in an aqueous environment. Improved surface conductivity should be explored using methods to produce a defect-free conductive surface. This could possibly be done using metal vapor deposition or other doping methods. It may also be possible to utilize conductive polymers to form a thick conductive layer. Heat resistant EAP would be desirable to allow operation at higher voltages without damaging the internal structure of the EAP due to the generation of heat in the EAP composite. Development of EAPs in different configurations (e.g., fibers and fiber bundles), would also be beneficial, in order to increase the range of possible modes of motion.

Famous quotes containing the words future and/or directions:
“The difference between Pound and Whitman is not between the democrat who in deep distress could look hopefully toward the future and the fascist madly in love with the past. It is that between the woodsman and the woodcarver. It is that between the mystic harking back to his vision and the artist whose first allegiance is to his craft, and so to the reality it presents.”
—Babette Deutsch (1895–1982)
“My friend devotes himself to his life, whenever he can find the spare time. His motto is: ‘Don’t just sit there: live!’ So he’s too busy to stand, to walk, to do anything, except to live. He even refused to kiss a girl, when invited, on the grounds that it was time again to be living. Schedules are sacred to him.”
—Marvin Cohen, U.S. author and humorist. The Self-Devoted Friend, New Directions (1967)
