- Abstract
- Actuators with muscle similar capabilities can provide new solutions to the industry and is a potential key factor in revolutionising prosthetic interventions after limb loss. To this date there have been developed rather few actuators with similar capabilities and functionality as skeletal muscles, where none yet has obtained a broader use. Intelligent materials show great potential in creating new actuators. Previous attempts in creating muscle similar actuators have in general been an effort of material science, resulting in a range of various materials; shape memory alloys, electro active polymers, piezoelectric ceramics and carbon nanotubes. A product design specification that described the material's fulfillment of specified design requirements was used to select one of the materials for further development. Actuators that can obtain similar capabilities as human skeletal muscles. However, the intelligent materials are in general lacking some main capabilities compared to skeletal muscles, whereas especially a sufficient strain proves to be the largest setback. Mechanisms that could amplify these intelligent materials' strain were therefore investigated. This lead to the development of a prototype of a multiplying mechanism, where the theoretical model of the design indicates that the final setup has potential to obtain the same capabilities as human skeletal muscles. Further development is however required, before a full scale test to prove that the concept can be performed. Though, data was assured, which may help guide any future development.
