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.

Natural muscles Two chapters by Gerald H. Virtually every known method of generating displacement is introduced.

Thomas give an excellent introduction as well as a detailed insight into the structure, mechanism and models for both materials and actuators. This distinction is due to the editor himself, and naturally the two classes of materials are described in two subtopics.

This book is a must for anyone interested in actuators and sensors, including physicians and biomedical, chemical, electrical, and material engineers. The efforts currently underway to model their nonlinear electromechanical behavior and develop novel experimental techniques to measure and characterize EAP material properties are discussed in Chapter 6.

Professor Paul Calvert from University of Arizona covers electroactive polymer gels. Modelling is of obvious importance — both for understanding fundamental properties and for predicting performance.

For power, the robot fish uses an inductive coil that is energized from the top and flectroactive of the tank. Both topics are devoted one chapter written by the editor and co-workers. 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.

Lesson learned, Applications and Outlook This is the summary remark by the editor. The next two chapters are more speculative in nature because the applications they describe have not been realised with EAP actuators yet.

EAP materials have a significant potential to improving our lives.

References to many reviews can however nuscles found in the chapter by Calvert. 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.

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

Light, flexible, noiseless actuators with stroke, force and efficiency similar to or better than that of human muscles are promises of polymer actuators. Lolymer 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. Ion-exchange membranes with chemically plated metal electrodes — ionomeric polymer metal composites IPMC — form one of the most studied polymer actuator systems.

Never the less the idea of designing molecules or super molecules, where structural changes is a molecular property polyjer than a materials property is intriguing. The similarity includes resilient, damage tolerant, and large actuation strains stretching, contracting, or bending. Instead, he gives a summary of methods within computational chemistry and polymer modelling.

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. 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.

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

He sums up the advantages and disadvantages of EAP materials, point to challenges to be overcome in the future development of EAP and reviews a long list of possible and actual application areas.


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. Structural reorganisation on the molecular level also occurs in a number of the other technologies, take an example: In order to exploit the electroactivf benefit that EAP materials can offer, researchers worldwide are now exploring the various aspects of this field.

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

This book is intended to serve as reference tool, a technology users’ guide, and a tutorial resource, and to create a vision for the field’s future direction. The authors call for standardised test methods and procedures and as a consequence call for an EAP infrastructure.

Furthermore, the system developed by Dr. The models accurately simulate experimental behaviour. This match may occur in the coming years, and the success of a robot against a human opponent will lead to a new era in both making realistic biomimetic robots and implementing engineering designs that are currently considered science fiction.
