Evaluates grasping performance in prosthetic fingers, suggesting enhanced stability and functionality.
In recent years, controlling multi-degree-of-freedom prosthetic hands through myoelectric recognition has enabled diverse hand movements. However, existing products mainly focus on reproducing degrees of freedom, overlooking the finger configuration essential for precision pinching, thus restricting grasping postures. This study aimed to enhance passive grasp stability by integrating flexible finger pads and joints in the thumb IP joint and the DIP joints of the index and middle fingers. This approach enabled precise grasping by allowing IP and DIP joint hyperextension and pad-based gripping. Improved grasping performance was validated through grasping experiments.
