6. Design: Biomaterials
 Variables
 Application: Structural, Therapeutic
 Location: Skeletal, Circulatory, Nervous Systems
 Duration: Patient life, Minutes

8. Design: Biomaterials
 Metals
 Ceramics
 Polymers
 Composites

10. Design: Mechanics
 Complex Analysis – Simple Motion

11. Design: Mechanics
 Inverse and Forward Dynamics
 Running Model

12. Prosthetics
 Artificial device that replaces a missing or non-
functioning limb
 External or Internal

14. Class Project
 Design a “Prosthetic Hand” using:
 string, straws, rubber bands, cardboard, washers,
hot glue gun, and/or duct tape

15. Design Considerations
 What is the Problem?
 Are you wanting to pick up a object?
 Grasp a ball?
 Background Research
 What are the previous designs?
 Number of fingers?
 Number of finger joints?
 Requirements
 Do you need to use all the materials?

16. Design Considerations
 Solutions
 Development Work
 Prototype
 Test and Redesign
