Electroactive Polymers as Artificial Muscles - Capabilities, Potentials and Challenges
نویسنده
چکیده
For many years, electroactive polymers (EAP) received relatively little attention due to the small number of available materials and their limited actuation capability. The recent emergence of EAP materials with large displacement response changed the paradigm of these materials and their potential capability. The main attractive characteristic of EAP is their operational similarity to biological muscles, particularly their resilience and ability to induce large actuation strains. Unique robotic components and miniature devices are being explored, where EAP serve as actuators to enable new capabilities. In recognition of the need for international cooperation among the developers, users and potential sponsors, an SPIE Conference was organized for the first time on March 1-2, 1999, in Newport Beach, California. The conference was the largest ever on EAP, and it marked an important milestone, turning the spotlight onto these emerging materials and their potential. Following this success, an MRS conference was initiated to address the fundamental issues related to the material science of EAP. The WW-EAP newsletter was initiated to bring the worldwide EAP community even closer. A homepage was also created to link worldwide EAP research and development facilities websites. In this paper, the current capabilities and potentials as well as the challenges of state-of-the art EAP will be reviewed.

متن کاملElectroactive Polymers as Artificial Muscles – Reality and Challenges
For many, the idea of a human with bionic muscles immediately conjures up images of science fiction -a superhuman character in a TV series. With bionic muscles, the hero is portrayed with strength and speed far superior to any normal human. As fantastic as that idea may seem, recent developments in electroactive polymers (EAP) may one day make such bionics possible. New effective EAP materials ...
متن کاملMuscle-like Actuators? a Comparison between Three Electroactive Polymers
Muscles fulfill several functions within an animal’s body. During locomotion they propel and control the limbs in unstructured environments. Therefore, the functional workspace of muscle needs to be represented by variables describing energy management (i.e. power output, efficiency) as well as control aspects (i.e. stiffness, damping). Muscles in the animal kingdom vary greatly with respect to...
