Wearable biopotential measurement using the TI ADS1198 analog front-end and tex...
Pereira, Tiago; Carvalho, Helder; Catarino, André P.; Dias, M. J.; Postolache, Octavian; Girão, Pedro S.The development of mobile systems for monitoring bioelectric signals outside a hospital environment involves many challenges that do not arise when it is in a controlled environment, like a hospital. The dimensions of these systems are an important factor to consider in order to facilitate their use without interfering with the daily activities of individuals. The purpose of this work is the implementation of a...
Integration of biosignal monitoring in sports clothing
Catarino, André P.; Rocha, A. M.; Carvalho, Helder; Montagna, Gianni; Dias, M. J.; Covas, Helder; Machado, R.; Villas-Boas, J. P.; Duarte, J.The present paper gives an overview of the developments achieved in biosignal and sports performance monitoring in the context of the Bioswim project. The Bioswim project aims at developing technologies for integration of conventional as well as embedding novel textile sensors for the measurement, recording and transmission of biometric and performance parameters for athlete monitoring. The study object has be...
Continuous health monitoring using e-textile integrated biosensors
Catarino, André P.; Carvalho, Helder; Dias, M. J.; Pereira, Tiago; Postolache, Octavian; Girão, Pedro S.In this work, continuous health monitoring for disabled or elderly people is proposed using textile integrated electrodes for ECG measurement. Other applications, such as EMG or skin impedance measurement are also envisaged. The paper specifically describes a shirt integrating electrodes for ECG measurement that has been tested in several conditions. The techniques for integration of ECG electrodes can be direc...
Surface electromyography using textile-based electrodes
Catarino, André P.; Carvalho, Helder; Barros, Luís; Dias, M. J.Surface Electromyography (sEMG) is a fundamental method for study the biomechanical behavior of a person, allowing the extraction of valuable information for health professionals. This paper presents a research conducted with the purpose of developing textile electrodes for noninvasive surface electromyography. Conducting fibers were used in a specifc arrangement taking into consideration SENIAM recommendations...
Biosignal monitoring implemented in a swimsuit for athlete performance evaluation
Catarino, André P.; Carvalho, Helder; Rocha, A. M.; Montagna, Gianni; Dias, M. J.Monitor athletes during exercise has always been a major challenge for engineers and researchers due to the restrictions involving the measurement of physiological and performance parameters. An athlete should have complete freedom to perform his normal activity, in order to be correctly monitored. The advent of e-textiles can give an important contribution to overcome these limitations since it is possible to ...
Aquisição de sinais electromiográficos recorrendo a eléctrodos em substratos tê...
Barros, Luís; Dias, M. J.; Carvalho, Helder; Catarino, André P.A electromiografia (EMG) constitui um método fundamental para o estudo do comportamento biomecânico de um indivíduo. Este artigo apresenta um estudo realizado na óptica do desenvolvimento de eléctrodos têxteis não invasivos para a realização de electromiografia de superfície. O trabalho apresenta um método de fabrico de eléctrodos, as suas vantagens e limitações e uma comparação entre dois tipos de eléctrodos t...
Clinical and molecular analysis of spinal muscular atrophy in Brazilian patients
Kim,C.A.; Passos-Bueno,M.R.; Marie,S.K.; Cerqueira,A.; Conti,U.; Marques-Dias,M.J.; Gonzalez,C.H.; Zatz,M.Spinal muscular atrophy (SMA), the second most common lethal autosomal recessive disorder, has an incidence of 1:10,000 newborns. SMA is divided into acute (Werdnig-Hoffmann disease, type I), intermediate (type II) and juvenile forms (Kugelberg-Welander disease, type III). The gene of all three forms of SMA maps to chromosome 5q 11.2-13.3. Two candidate genes, the survival motor neuron (SMN) gene and the neuron...
