Today I read a paper titled “Bionic Humans Using EAP as Artificial Muscles Reality and Challenges”
The abstract is:
For many years, the idea of a human with bionic muscles immediately conjures up science fiction images of a TV series superhuman character that was implanted with bionic muscles and portrayed with strength and speed far superior to any normal human
As fantastic as this idea may seem, recent developments in electroactive polymers (EAP) may one day make such bionics possible
Polymers that exhibit large displacement in response to stimulation that is other than electrical signal were known for many years
Initially, EAP received relatively little attention due to their limited actuation capability
However, in the recent years, the view of the EAP materials has changed due to the introduction of effective new materials that significantly surpassed the capability of the widely used piezoelectric polymer, PVDF
As this technology continues to evolve, novel mechanisms that are biologically inspired are expected to emerge
EAP materials can potentially provide actuation with lifelike response and more flexible configurations
While further improvements in performance and robustness are still needed, there already have been several reported successes
In recognition of the need for cooperation in this multidisciplinary field, the author initiated and organized a series of international forums that are leading to a growing number of research and development projects and to great advances in the field
In 1999, he challenged the worldwide science and engineering community of EAP experts to develop a robotic arm that is actuated by artificial muscles to win a wrestling match against a human opponent
In this paper, the field of EAP as artificial muscles will be reviewed covering the state of the art, the challenges and the vision for the progress in future years
