Research & Labs > Projects > Functional Finger Learning Tool |
|
The Functional Finger Learning Tool was designed and built by three MAE students with the help of SJSU professor Dr. Ji C. Wang, and was the winner of 2008 ASME Regional Old Guard Competition. Funding for the Functional Finger project was obtained by the College of Engineering through the Professional Development Grant Award, ASME Old Guard Oral Competition, and Best Technical Content Award.
The objective of this project was to create a functional model
of one of these mechanisms, the index finger. It is believed
that such a model could be used as a learning tool by complimenting anatomical drawings and possibly replacing cadaveric models. |

When developing the first prototype, considerations were given to the shape of the bones, joint types, pivot points, associated muscles groups, tendon pathways, tendon connection points, volar plates, and an electromechanical control system. Accommodations were made to each of the above in order to obtain functionality, but future research, design, and support
will help to minimize discrepancies between the model and an actual human finger. |

CT scans of a human hand were procured from a representative at Materialise. Materialise software, Mimics,
was used to convert the bones to a format readable by rapid prototype machines (.stl). The bones were then printed in plastic on one of the MAE department's rapid prototype machines. (Thank you Dr. Yee)
Considerations were applied during prototype assembly and the model was tested alongside a video of a functional cadaveric model. Click here to watch video! |
