Defining Requirements and Related Methods for Designing Sensorized Garments
Designing smart garments has strong interdisciplinary implications, specifically related to user and technical requirements, but also because of the very different applications they have: medicine, sport and fitness, lifestyle monitoring, workplace and job conditions analysis, etc. This paper aims to discuss some user, textile, and technical issues to be faced in sensorized clothes development. In relation to the user, the main requirements are anthropometric, gender-related, and aesthetical. In terms of these requirements, the user’s age, the target application, and fashion trends cannot be ignored, because they determine the compliance with the wearable system. Regarding textile requirements, functional factors—also influencing user comfort—are elasticity and washability, while more technical properties are the stability of the chemical agents’ effects for preserving the sensors’ efficacy and reliability, and assuring the proper duration of the product for the complete life cycle. From the technical side, the physiological issues are the most important: skin conductance, tolerance, irritation, and the effect of sweat and perspiration are key factors for reliable sensing. Other technical features such as battery size and duration, and the form factor of the sensor collector, should be considered, as they affect aesthetical requirements, which have proven to be crucial, as well as comfort and wearability
Desenvolvimento de uma plataforma para Internet das Coisas baseada em Wi-Fi
Dissertação de Mestrado Ciclo de Estudos Integrados Conducentes ao Grau de Mestre em Engenharia de Telecomunicações e InformáticaO principal objetivo desta dissertação visa o desenvolvimento de uma
plataforma genérica para a Internet das Coisas. Para o desenvolvimento da
plataforma genérica recorreu-se à utilização de um dispositivo Arduino e de um
módulo Wi-Fi. O Arduino tem como objetivo permitir interligar sensores utilizando
para isso as interfaces de comunicação disponibilizadas, sendo elas a interface UART,
I2C, SPI e ADC.
A interface de comunicação usada para realizar a comunicação entre o Arduino e
o módulo Wi-Fi escolhido (ESP8266) é a interface UART. Para a implementação do
sistema, desenvolveu-se um firmware para o módulo ESP8266, que permite realizar
a conexão do módulo Wi-Fi a qualquer rede Wi-Fi presente nas imediações do
módulo ESP8266.
Esta dissertação tem um segundo objetivo que foi realizado em parceria com um
aluno do Mestrado Integrado em Eletrónica Industrial e Computadores (MIEEIC) cujo
tema de dissertação é o desenvolvimento de um sistema de monitorização de
consumos e de qualidade de energia elétrica (QEE). Neste segundo objetivo foi
desenvolvido um protocolo de comunicação para recolha de dados dos monitores de
QEE e uma aplicação para PC (Personal Computer) para realizar a apresentação dos
valores recolhidos. O sistema usado para realizar a comunicação entre os monitores
QEE e a aplicação desenvolvida para o utilizador é a plataforma genérica para a
Internet das Coisas.
O projeto realizado nesta dissertação foi concluído com sucesso, sendo
comprovado o correto funcionamento da plataforma genérica para a Internet das
Coisas. A plataforma desenvolvida permite realizar a devida interação entre os
sensores e a aplicação do utilizador. Toda a programação desenvolvida para a
plataforma genérica foi devidamente testada, bem como a aplicação desenvolvida para o utilizador para interação com o monitor de QEE, apresentando bons
resultados.The main objective of this dissertation is the development of a generic platform
for the Internet of Things. For the development of the generic platform, an Arduino
device and a Wi-Fi module were used. The Arduino device allows the interconnection
of sensors using the available communication interfaces, such as UART, I2C, SPI and
ADC.
The communication interface used to perform the communication between the
Arduino and the chosen Wi-Fi module (ESP8266) is the UART interface. For the
implementation of the system, a firmware was developed for the ESP8266 module,
which allows the connection between the Wi-Fi module and the Wi-Fi network
present near the ESP8266 module.
This dissertation has a second objective that was done in partnership with a
student of the Integrated Master’s in Industrial Electronics and Computers (MIEEIC)
whose dissertation theme is the development of a system for monitoring of
consumption and power quality (PQ). In this second objective it was developed a
communication protocol for data collection of the PQ monitors and a PC (Personal
Computer) application to perform the presentation of the collected values. The
system used to communicate between PQ monitors and the application developed
for the user is the generic platform for the Internet of Things.
The project done in this dissertation was successfully completed and the correct
functioning of the generic platform developed for the Internet of Things was
demonstrated. The developed platform allows the interaction between the sensors
implemented in the generic platform and the User. All the developed code for the
generic platform was properly tested, as well as the application developed for the
user for interaction with the PQ monitor, presenting good results
