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

Gerwin Smit, MSc, PhD, et al.

Current body-powered (BP) prosthetic hands have stiff fingers and require a large amount of input energy by the prosthesis user to produce a limited pinch force at the fingertip. Two new finger prototypes were designed, constructed, and evaluated. One finger was driven by a pulley and a cable; the other was driven by a hydraulic cylinder. The fingers enable the construction of an articulating BP prosthetic hand that is lighter, can pinch harder, and has a higher energy efficiency than current BP prosthetic hands. Of both tested fingers, the hydraulic cylinder finger is the most suitable because it requires less input energy.
