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...
O designer de produto como elemento de ligação nas equipas multidisciplinares
Montagna, Gianni; Carvalho, Cristina; Carvalho, Helder; Catarino, André P.A possibilidade de manter os mais importantes elementos do design criados pelo designer será possível através de uma mistura de estratégia e conhecimento que o designer deverá ser capaz de gerir da maneira mais proveitosa. O comportamento individual e reservado, geralmente assumido e projetado aos outros intervenientes no processo de desenvolvimento de novos produtos, por parte do designer, já não são suficient...
Treat me well : affective and physiological feedback for wheelchair users
Postolache, Octavian; Girão, Pedro; Ribeiro, Mário; Carvalho, Helder; Catarino, André P.; Postolache, GabrielaThis work reports a electrocardiograph and skin conductivity hardware architecture, based on E-textile electrodes, attached to a wheelchair for affective and physiological computing. Appropriate conditioning circuits and a microcontroller platform that performs acquisition, primary processing, and communication using Bluetooth were designed and implemented. To increase the accuracy and repeatability of the ski...
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...

Proposal of tubular technical drawing for creation of seamless clothing
Magnus, E.; Broega, A. C.; Catarino, André P.The present paper suggests an approximation between seamless technology and fashion design by proposing a tool for creating garment, with the final goal of reducing the gap between creative and technical professionals. It is intended to help the optimization of the creative activity together with the technical action, using a technical drawing in form of a circular tube, which will facilitate the communication ...
Ergonomic garment design for a seamless instrumented swimsuit
Montagna, Gianni; Carvalho, Helder; Catarino, André P.; Silva, Fernando Moreira da; Albuquerque, HeloísaIn the relationship of the human body with the environment, there is no doubt that garments are the most used medium and the most widespread way of communication. In sports garments and in technical apparel, the relationship with the user is even closer, in order to obtain better results and an advantage that could derive from the best combination between the user and the study object. In this paper, the study ...
Throughput limits of two 802.15.4 wireless networks applications for signal acq...
Alves, Joel; Catarino, André P.; Carvalho, Helder; Monteiro, João L.; Rocha, A. M.This work describes the development and test of a wireless sensor network used by a biomedical signal monitoring system. Data communication is based on a body area network (BAN) materialized as a wireless network in two versions, one based on the 802.15.4 specification and another on a higher-level Zigbee protocol. The system was developed using the Jennic JN5148 microcontroller, Jennics ZBPro stack and the Jen...
