  Simulação de uma prótese mioelétrica e controle do videogame Tetris usando sinais EMG, Descrição: O projeto envolve a identificação de cinco tipos de movimentos: extensão, flexão curta, flexão completa, virar à esquerda e virar à direita. Foi desenvolvido um hardware para realizar a aquisição das sinais EMG do bíceps do usuário e foi programada uma interface para simular a execução dos movimentos identificados e um videogame tipo Tetris controlado pelos movimentos do usuário.. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (1) . , Integrantes: Wilmer Johan Lobato Malaver - Coordenador / Ronald Kuijpers - Integrante / Sergio Salas - Integrante., Número de produções C, T & A: 1

Projetos de desenvolvimento

• 2013 - 2013

  A Low-Cost Acquisition System for Heat Beat Measurement in Ubiquitous Healthcare Environment, Descrição: The aim of this work is to design a system capable of measuring heart beat intervals from both heart sounds and electric signals, as well as temperature from a sensor. A wearable device was developed consisting of two steps: signal acquisition and conditioning, providing digital pulses for each heart beat and an analog level for the temperature, and a signal processing and transmission, formatting the signals into a message transmittable via Bluetooth. Another two stages were developed in software, for receiving the information and presenting data. Two receiving options were implemented: a desktop computer and a mobile device. In the case of desktop computer, a software receives the messages and recovers the data, making it available as a HTTP server. A web application, written in PHP, reads this data and presents in viewable formats. In the case of mobile device, an android application performs both stages, presenting the last updated measures in real time. Flaws in the system were identified concerning stability of ECG acquisition, mostly caused by poor assembly of the prototype. However, successful tests were conducted.. , Situação: Concluído; Natureza: Desenvolvimento. , Alunos envolvidos: Mestrado acadêmico: (3) Doutorado: (1) . , Integrantes: Wilmer Johan Lobato Malaver - Coordenador / janio anselmo - Integrante / William Castañeda - Integrante / Mohammed Sawan - Integrante / Fernando Cosentino - Integrante.
