Projeto e Execução de Ponte Extensionétrica para Medição de Deformação em Próteses de Membros Inferiores

Abstract

The project developed an Extensometric Bridge to measure deformations in lower limb prostheses, using strain gauge sensors and a PIC microcontroller. The system converts voltage variations into deformations, displaying the data on an LCD and computer via RS232 serial communication. Simulations were performed in Proteus software, codes were developed in C, and a Delphi program was created for data visualization. The aim was to evaluate the behavior of prostheses under static and dynamic loading, contributing to the validation of their mechanical properties.
