| Summary: | Virtual prototyping can assist in determining the probability of success for newly generated concepts within the assistive technology domain. The notion of using musculoskeletal movement or electronically powered systems is well established within this field. However, if these systems need to be controlled, as well as powered then issues in terms of affordability, robustness or applicability can arise. A device that is powered and controlled by breathing could expand the product options for patients and address certain requirements that are difficult to meet with current devices. Prosthetics provide a good proving ground for this novel concept. The aim of the study is to develop a virtual prototype to assess the possibility of powering and controlling an artificial hand through breathing. The virtual prototype will follow a modular analysis. Models will be generated for respiratory airflow, turbine performance, torque transmission and pinch force of the terminal device. The virtual prototype results indicate that a breathing powered prosthetic can generate enough force to complete certain activities of daily living.
