This is a prosthesis for people that has lost his entire thumb. It's an articulated thumb, with silicone tip, connected by a wire to the index finger. When the index flexes, it flexes the thumb, this way the person is able to grip things of different diameters and perform tip grip.

The mechanism was inspired in the one used in the Cyborg Beast.

This object was made for the "Mutual de Seguridad C.Ch.C" from Chile. In a project of the Direction of innovation and development, and the Neuro rehabilitation institute.

A video of the prosthesis begin tested (a former prototype) can be found in https://youtu.be/vKrV3-DOdA4
