Analyzing Work and Hysteresis in Prosthetic Finger Movement

This study focuses on how work is represented by the area under a force-path curve in prosthetic finger design. The hysteresis or energy dissipated by the finger is calculated as the difference between the work done during closing and the elastic energy returned during reopening. The research evaluates different finger concepts for body-powered prosthetic hands, considering factors like energy efficiency and mechanical design. Adapted from a study by Smit and Plettenburg, this work provides insights into optimizing prosthetic finger mechanisms for improved functionality and user experience.

  1. Figure 2. Work can be represented by area below force-path curve.(a) Hysteresis or energy dissipated by finger (Ehys) is difference between (b) work done on finger during closing (Eclose) and(c) elastic energy returned by finger during reopening (Eelastic).
