ELECTROACTIVE POLYMER EAP ACTUATORS AS ARTIFICIAL MUSCLES PDF

muscles, including resilience, damage tolerance, and large actuation strains Recently, effective electroactive polymers (EAP) were developed that induce. Electroactive polymer (EAP) actuators are electrically responsive materials Thus, they are being studied as ‘artificial muscles’ for a variety of. actuators. The main attractive characteristic of. Electroactive polymers. (EAP) is their operational similarity to biological muscles, particularly their resilience.

Chris Thomas and Mr. The editor would like to thank everyone who contributed to his efforts, both as part of his team advancing the technology as well as those who helped with the preparation of this book.

References to many reviews can however be found in the chapter by Calvert. The various classes of EAP materials are clearly classified according to their mechanism of actuation, and an effort is done to survey the weakness and strengths of the various polymer actuator materials and technologies.

EAP materials have a electroative potential to improving our lives. Chapter 3 covers the leading EAP materials and the principles that are responsible for their electroactivity. It has more the form of a research paper than a review, but interesting work on dielectric elastomer actuators can be found here.

The editor himself writes both.

Such efforts are leading to a better understanding of the origin of the electroactivity of various EAP materials, which, in turn, can help improve and possibly optimize their performance. Also, not all areas of polymer actuators are given equal attention.

Satoshi Tadokoro, Kobe University, Japan, for his analytical modeling effort. If EAP materials can be developed to the level that they can compete with natural muscles, drive prosthetics, polyjer as artificial muscle implants into a human body, and become actuators of various commercial products, the developers of EAP would make tremendously positive impact in many aspects of human life.

Marsella from University of California at Riverside describe materials, where huge structural changes occur in a single molecule under activation.

The advances were not only marked with the first commercial product; there has also been the announcement by the SRI International scientists who are confident they have reached the point that they can now meet the challenge posed by this book’s editor of building a robot arm with artificial muscles that could win an arm wrestling match against a human.

Thus, polymer-based EAP-actuated devices may be fully produced by an ink-jet printing process enabling the rapid implementation of science-fiction actyators e.

Polymers are a promising alternative to materials commonly used for actuators, such as piezoelectric ceramics, shape memory alloys, magnetostrictive materials, and electrorheological fluids. Their contribution is highly appreciated and it helped making this book of significantly greater value to the readers:.

Never the less the idea of designing molecules or super molecules, where structural changes is a molecular property rather than a materials property is intriguing. A special thanks to Dr. This actuuators gives a thorough introduction as well as in-depth descriptions of the many aspects of polymers as actuators.

The book is the first attempt to give a full review of the state-of-the-art within polymer actuators. This is an ongoing dispute among muscle researcher.

Electroactive polymer actuators as artificial muscles: are they ready for bioinspired applications?

This is the summary remark by the editor. DEA is an electrostatic actuator and perhaps the polymer actuator, whose functionality has the least resemblance to natural muscles of all.

Following the reported progress and milestones that were reached in this field has been quite heartwarming.

Reality, Potential, and Challenges Editor s: Their many unique characteristics can make them a valuable alternative to current actuators such actuatore electroactive ceramics and shape memory alloys. Methods of effective control are addressing the unique and challenging aspects of EAP actuators. Furthermore, the system developed by Dr.

Instead, he gives a summary of methods within computational chemistry and polymer modelling. Richard Claus, VT; Actuatods. This book electroactivw a must for anyone interested in actuators and sensors, including physicians and biomedical, chemical, electrical, and material engineers. Modeling the behavior of EAP materials requires the use of complex analytical tools, which is one of the major challenges to the design and control of related mechanisms and devices.

On the positive side, there has already been a series of reported successes in demonstrating miniature manipulation devices, including a catheter steering element, robotic arm, gripper, loudspeaker, active diaphragm, dust-wiper, and many others.

Electroactive polymer actuators as artificial muscles: are they ready for bioinspired applications?

It should be noted however that the paper focus on polymer gels as artificial muscles and they are certainly not the main focus for most researchers working with polymer actuators today. This book covers EAP from all its key aspects, i. The reader should realize however, that conjugated polymers have been studied for decades and a whole book could have been attributed to the description of those materials.

Lesson learned, Applications and Outlook This is the summary remark by the editor. EAP materials are parted into two classes: Although the dispute itself is somewhat irrelevant for researchers developing polymer actuators, it helps highlighting the resemblance and differences between polymer actuator and natural muscle behaviour.

It is as pleasure to read these chapters, and I will certainly recommend the book to all who has an interest in this fascinating new technology. The book can certainly be recommended to newcomers, mucsles want to get a broad overview, and it will also serve as a reference book for experts, who already work with polymer actuators.
