Abstract
This paper describes the use of a Fiber Bragg Grating (FBG) sensor to control an automated arm prosthesis. The FBG sensor measures the subject forearm muscle deformation caused by the index and middle finger movement. By analyzing the forearm movement signal, it is possible to control an one joint model prosthesis allied to a compliant hand mechanism. Each finger movement is transduced in one type of prosthesis action, joint rotation, and compliant hand by the middle and index fingers, respectively. In this paper are presented preliminary results regarding the prosthesis assembling and tests with pre-acquired and processed data. The results show the possibility of the sensor system and the automated prosthesis use in further applications with online forearm sensing and prosthesis movement.
