  1. Manotech Associates Low-Cost Prosthetic Hand February 9, 2006 Jina Kim Forrest Liau David Lin Kelsey Vandermeulen Teresa Wang

  2. Motivation • In low-income communities, hands important • Accidents and civil war --> amputation • Cosmetics highly valued • Functional body important for status in society

  3. Functional Complex system Current Solutions • Purely cosmetic R. Doshi, Stanford University www.ossur.com

  4. How Can We Help? • Novel mechanical design  • Not our expertise • Much prior art exists • Underlayer material  • Skin  • Fingernail  Focus on one or more of these

  5. Area of Innovation • Customizable aesthetics • Underlayer • Size • Shape • Skin • Color • Texture • Fingernail • Size/shape/color/texture

  6. Concepts for Size/Shape Customization • Do-it-yourself custom mold • Inexpensive factory-made mold sets • Adjustable mold (?)

  7. Concepts forColor Customization • Heat treatment • Chemical treatment • Paint/spray/coat

  8. Concepts forTexture Customization • Heat treatment • Chemical treatment • Abrasion • Printing • Manual application

  9. Work Plan Overview • Determine specs and desired properties • Research materials • Test materials • Assess feasibility of concepts • Prototype prosthetic hand • Test prototype

  10. General Schedule Design Review Mid-term Review Initial Prototype Final Presentation

  13. Underlayer Engineering • Desired Material Properties • Durable and lightweight • Shapeable for easier processing • Process • Option 1: • Use a relative’s hand for customization • Requires low-cost, quick-drying material • Option 2: • Use CAD and 3D printing to create different-sized molds • More flexibility in selecting the mold material

  14. Skin Engineering • Desired Material Properties • Liquid, spray, or thin films • Possibly disposable • High melting temperature • Waterproof, elastic • Bonds well (chemically, preferably) to underlayer • Process • Liquid “skin”: • Dip underlayer into liquid and allow it to dry • Paint underlayer • Spray: • “Spray-on” skin • Consumer-friendly, convenient

  15. Prosthetic Production • Considerations • Color: prosthetic matches natural skin tone • Shape: depends on user’s age and size • Texture: to allow for gripping • Product Option 1: underlayer only • Simpler processing • Product Option 2: underlayer + skin • Skin can be replaced, instead of entire prosthetic • Less concern about underlayer appearance, allowing for greater range of material options

  16. Testing • Durability • Expose prototype to heat and water • Material contact with environment (dirt, animal hair, crops) • Determine time frame of wearing out • Social acceptance • Survey prototype “authenticity” in affected populations
