Design and evaluation of two different finger concepts for body-powered prosthetic hand

This study aims to find an efficient energy transmission method for body-powered prosthetic hands. Two different finger concepts - pulley-cable finger and hydraulic cylinder finger - were designed and tested. The results showed that the hydraulic cylinder transmission was more efficient in delivering pinch force with less input energy, especially for tasks requiring higher pinch forces.

  1. Design and evaluation of two different finger concepts for body-powered prosthetic hand Gerwin Smit, MSc, PhD; Dick H. Plettenburg, MSc, PhD;Frans C. T. van der Helm, MSc, PhD

  2. Aim • Find efficient energy transmission method for body-powered prosthetic hand. • Relevance • Mechanisms in prosthetic hands should have low mass and be able to deliver pinch force with only small amount of input energy.

  3. Method • Designed and tested pulley-cable finger and hydraulic cylinder finger. • Compared pulley-cable transmission principle with hydraulic cylinder transmission principle. • Both fingers had identical dimensions and low mass. • Measured input energy for several tasks. (b) (a) Figure. (a) Pulley-cable finger.(b) Hydraulic cylinder finger.

  4. Results • Pulley-cable finger required more input energy than hydraulic cylinder finger to perform tasks, especially tasks requiring higher pinch forces.

  5. Conclusion • Hydraulic cylinder transmission is more efficient transmission for application in body-powered prosthetic fingers.
