MYOLECTRIC PROSTHETIC (WIP)

a.k.a The "Growing" Prosthetic

The goal of this project is to create a working prototype of an inexpensive extendable "below the elbow" prosthetic for children which can be 3D printed. The fore arm will increase in length as well as in width in order to compensate for a child's growth. This product enables proper development of motor skills, promotes positive body image, and reduces costs and doctor's visits.

The first stage will include the forearm, hand, and circuitry which allows the hand to open and close when the corresponding nerve impulse is detected. This project is in collaboration with a local amputee. The next stage would be to include a mobile wrist joint​ and incorporate user feedback.

HAND ASSEMBLY

​

HAND (BODY)

This part of the hand serves as the body of the hand.
This section is representative of the Carpal and Metacarpal bones combined.

METACARPOPHALANGEAL JOINT (MCP)

This part represents the Metacarpophalangeal Joint that connects the proximal phalange to the metacarpal bone.

PROXIMAL AND DISTAL INTERPHALANGEAL
(PIJ / DIJ)

This joint represents the Interphalangeal Joint that connects the proximal phalange to the intermediate phalange (PIJ), and the intermediate phalange to the distal phalange (DIJ).
