Prosthetic Hand

Project Overview

Developed through the university's biomedical engineering club, this prosthetic uses a Bowden cable actuated by wrist flexion to drive all four fingers simultaneously. The modular design allows individual fingers to be replaced without tools. Five volunteer testers provided usability feedback that informed three major design iterations.

Key Highlights

• 12 N grip force achieved with standard cable tension
• Entire assembly printable on an FDM printer in under 8 hours
• Modular finger snap-fit design — no tools required for replacement
• Three design iterations driven by user testing feedback
• Bill of materials under $35 USD in materials
