FMG-Controlled Prosthesis for Below-Elbow Amputees

The challenge

Most advanced prosthetic arms are expensive, complex, and not accessible to many users. Simpler prostheses often lack real functional control.

This project provides a low-cost and simple solution that enables intuitive control of a prosthetic hand.

Who it helps

Below-the-elbow amputees who seek a more comfortable alternative to mechanical harness-operated prostheses.

We worked with our Need-Knower, Maximiliano David Sidelski, throughout the development process to ensure the solution fits real-life needs.

How it works

It is low-cost, simple, and easy to use, with personal calibration for each user. The system is also compatible with standard government-issued prosthetic arms, making it an accessible and practical solution for a wide range of amputees.

We developed a low-cost Force Myography (FMG)-based control system that uses a single force sensor to detect forearm muscle contractions and trigger a servo motor for pinch grip.The servo motor is mounted according to Bionic Prosthesis project on TOM.
