ELECTROACTIVE POLYMER EAP ACTUATORS AS ARTIFICIAL MUSCLES PDF

  • June 14, 2019

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.

Advances reported in this second edition include an improved understanding of these materials’ behavior, better analytical modeling, as well as more effective characterization, processing, and fabrication techniques. World leading experts — G. It is thorough in every way Chapter 4 covers such fundamental topics as computational chemistry and nonlinear electromechanical analysis to poly,er their behavior, as well as a design guide for the application of an example EAP material.

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

The change in this view occurred in the early s, as a result of the development of new EAP materials that exhibit a large displacement in response to electrical stimulation. The chapter written by Dr.

Certainly, this is an interesting application and certainly electrorheological fluids are smart materials, but they are not really EAP materials. Musclee three is parted into one more subtopic: Methods of effective control are addressing the unique and challenging aspects of EAP actuators. The book is the first attempt to give a full review of the state-of-the-art within electroqctive actuators. DEA is an electrostatic actuator and perhaps the polymer actuator, whose functionality has the least resemblance to natural muscles of all.

Lesson learned, Applications and Outlook This is the summary remark by the editor. Testing and Characterisation Both topics are devoted one chapter written by the editor and co-workers. Professor Paul Calvert from University of Arizona covers electroactive polymer gels. Sean Leary, Mark Schulman, Dr.

Natural muscles Two chapters by Gerald Electroachive.

Also, not all areas of polymer actuators are given equal attention. The reader is guided through the wider area of smart structures and materials. Stewart Sherrit for their help.

They focus on electrostrictive polymers, mainly PVDF co-polymers, and shortly describe dielectric elastomer actuators and electrets. Instead, he gives a summary polhmer methods within computational chemistry and polymer modelling.

A device may be fully produced in 3D detail, thereby allowing rapid prototyping actuator subsequent mass production possibilities. The book can certainly be recommended to newcomers, who want to get a broad overview, and it will also serve as a reference book for experts, who already work with polymer actuators.

Professor Shahinpoors group from Univ. The editor would like to acknowledge and express his appreciation to the following individuals, who took the elctroactive to review various book chapters of the first ekectroactive and particularly those who where not coauthors of this book. Furthermore, the system developed by Dr. EAP materials have a significant potential to improving our lives. It covers the developments up to In Decemberthe Japanese company Eamex produced a robot fish that swims in a water tank without batteries or a motor.

In preparing this second edition, efforts were made to update the chapters with topics that have sustained major advances since the first edition was prepared three years ago. The beauty of the paper is that it describes the use of the models for simulating complex applications like a soft micromanipulation device with 6 degrees of freedom. This rather short chapter gives a good introduction to volume responsive gels, but it does not describe the whole area of polymer gels actuators in the details it deserves.

It has more the form of a research paper than a review, but interesting work on dielectric elastomer actuators can be found here. 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.

Their contribution is highly appreciated and it helped to make this book of electroacitve greater value to the readers:.

This book is a must for anyone interested in actuators and sensors, including physicians and biomedical, chemical, electrical, and material engineers. One of the books strengths is an excellent introductory chapter to EAP materials and actuators. Full, Kenneth Meijer from University of California at Berkeley gives an indispensable background on the structure and actuatogs of natural muscles. However, before these materials can be applied as actuators of practical devices their actuation force and robustness will need to be increased significantly from the levels that are currently exhibited by the available materials.

This performance, combined with the low cost and wide range of manufacturing methods of polymer materials, suggest a wide range of potential applications. Also, the whole field of microfabrication of polymer actuators is sparsely touched on.

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

Calvert, University of Arizona, for the information about biological muscles. The second subtopic describes four different ionic EAP materials: Chapter 1 of electroacyive book provides an overview and background to the various EAP materials and their potential. 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. It is shown that a dielectric elastomer actuator DEA behaves reasonably muscle like simply because it is soft and viscoelastic.

Potential beneficiaries of EAP capabilities include commercial, medical, space, and military that can impact our life greatly.

Generally, EAP actuators are highly agile, lightweight, low power, mass producible, inexpensive, and possess an inherent capability to host embedded sensors and microelectromechanical systems MEMS.

This eqp one single chapter, but it is with good reasons that the editors choose to present it in a separate subtopic. Some chapters in the last part of the book deal with topics not special to polymer actuators — or no developments within polymer actuators have taken place within these areas. To some extend the editor have created this on the EAP web site. This book reviews the state of the art of the field of electroactive polymers EAPswhich are also known as artificial muscles for their functional similarity to natural muscles.
