Desenvolvimento de prótese modelo controlada por sensor do tipo rede de Bragg em fibra ótica

Abstract

This work presents the application of a fiber optic Bragg Network sensor to control an automated arm prosthesis. The sensor, which is attached to an individual’s forearm, measures the deformation caused in the optical fiber by the movements of the index and middle fingers. Analyzing the signal generated by the deformation of the fiber, it was possible to develop a one joint prosthesis combined with a compliant mechanism. The movement of each finger was transduced into a type of prosthesis action, joint rotation and movement of the compliant mechanism, by the middle and index fingers, respectively. In the text you will find details about the modeling of the prosthesis, analysis of the signal generated by the sensor and the development of software for control and data exchange.
