• 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.

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.

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