Engineer creates prosthetic hand that GROWS with its user

A student from the Warsaw University of Technology is leading a team to create a hand prosthesis that grows with its user.

Ewelina Drelich, a graduate of engineering studies at the Faculty of Power and Aeronautical Engineering, and currently a student of the Faculty of Electronics and Information Technology, came up with the idea for the hand prosthesis with cheap, interchangeable parts for her engineering thesis.

Drelich said: “While preparing earlier for the interim project, in which I made a biological model of a hand, I got acquainted with the literature and research on the hand, its movements and prostheses.

The idea behind making the mechanics that operate the prothesis modular was to allow access to as many people as possible. Prothesis that can operate with similar functionality to an arm and hand can cost between $20,000 and $100,000, making them unobtainable for most families. When a child is growing rapidly and requires adjustments or new prothesis this can exacerbate the financial problem.

The solution to make the components interchangeable will help those who need to adapt or grow their existing prothesis do so in a more affordable way than purchasing a completely new model.
