Chapter 19 – A NEW FRONTIER FOR ORTHOTICS AND PROSTHETICS: APPLICATION OF DIELECTRIC ELASTOMER ACTUATORS TO BIONICS

Dielectric elastomer actuators (DEAs) whether used as artificial muscles or as replacements for traditional actuators show great potential for use in modern active orthotic and prosthetic therapeutic applications. Such actuators are roughly similar in function and biomechanics to natural muscle, including the ability to produce the high peak power density needed for muscle-like actuation that can simplifying biomimetic and bio-inspired design. Furthermore, DEAs are also capable of multidirectional actuation, enabling novel external and implantable designs not as suited to traditional actuation technology. Examples include artificial muscle-powered prosthetic arms, active ankle-foot orthoses, and ventricular assist devices. While challenges currently exist in using dielectric elastomerbased actuators for biomedical use, this technology shows great potential for the development of advanced orthoses and prostheses, leading to a substantial benefit for those with physical impairments and disabilities.
