“…The calibration curve simulated for the transmittance mode PPG system was compared with the empirical calibration curve of a commercial pulse oximeter for reference. The relationship between the oxygen saturation measured by the commercial pulse oximeter (SpO2) and the ratio of ratios R is presented by the equation for the standard calibration curve: SpO2=110−25R which has been extensively used in many applications of pulse oximetry [2,50,51,52,53]. In general, commercial pulse oximeters are calibrated empirically within the oxygen saturation range of 70–100%.…”

Photoplethysmography (PPG) is a non-invasive photometric technique that measures the volume changes in arterial blood. Recent studies have reported limitations in developing and optimising PPG-based sensing technologies due to unavailability of the fundamental information such as PPG-pathlength and penetration depth in a certain region of interest (ROI) in the human body. In this paper, a robust computational model of a dual wavelength PPG system was developed using Monte Carlo technique. A three-dimensional heterogeneous volume of a specific ROI (i.e., human finger) was exposed at the red (660 nm) and infrared (940 nm) wavelengths in the reflectance and transmittance modalities of PPG. The optical interactions with the individual pulsatile and non-pulsatile tissue-components were demonstrated and the optical parameters (e.g., pathlength, penetration depth, absorbance, reflectance and transmittance) were investigated. Results optimised the source-detector separation for a reflectance finger-PPG sensor. The analysis with the recorded absorbance, reflectance and transmittance confirmed the maximum and minimum impact of the dermis and bone tissue-layers, respectively, in the formation of a PPG signal. The results presented in the paper provide the necessary information to develop PPG-based transcutaneous sensors and to understand the origin of the ac and dc components of the PPG signal.

“…In the absence of medical staff, the users can detect abnormalities and take necessary first aid action on the basis of measured and reference values. These values are important and must be known to the common person, which is why they are extracted and reproduced in this article instead of referring the reader to [ 125 ]. The readers who belong to the medical domain may refer to [ 126 , 127 ] for an in-depth study of human physiology, but it is beyond the scope of our study.…”

The deployment of wearable or body-worn devices is increasing rapidly, and thus researchers’ interests mainly include technical and economical issues, such as networking, interoperability, security, power optimization, business growth and regulation. To address these issues properly, previous survey papers usually focused on describing the wireless body area network architecture and network protocols. This implies that deployment issues and awareness issues of wearable and BAN devices are not emphasized in previous work. To defeat this problem, in this study, we have focused on feasibility, limitations, and security concerns in wireless body area networks. In the aspect of the economy, we have focused on the compound annual growth rate of these devices in the global market, different regulations of wearable/wireless body area network devices in different regions and countries of the world and feasible research projects for wireless body area networks. In addition, this study focuses on the domain of devices that are equally important to physicians, sportsmen, trainers and coaches, computer scientists, engineers, and investors. The outcomes of this study relating to physicians, fitness trainers and coaches indicate that the use of these devices means they would be able to treat their clients in a more effective way. The study also converges the focus of businessmen on the Annual Growth Rate (CAGR) and provides manufacturers and vendors with information about different regulatory bodies that are monitoring and regulating WBAN devices. Therefore, by providing deployment issues in the aspects of technology and economy at the same time, we believe that this survey can serve as a preliminary material that will lead to more advancements and improvements in deployment in the area of wearable wireless body area networks. Finally, we present open issues and further research direction in the area of wireless body area networks.

“…The main goal of [14] was to create a Wearable Wireless Body Area Network (WWBAN) to monitor the health of elderly and disabled people using a pulse oximeter, heart rate, temperature, hydration, glucose level, and fall detection sensors, Arduino microcontroller, LCD display, and GSM (Global System for Mobile communication) modem. As a result, to collect, analyze and process all the data from the sensors, they were connected to the Arduino and displayed on the LCD.…”

“…F. Ullah, A. Iqbal, et al [15] had a similar concept to [14], but instead of elders and disabled people, the authors built a framework for physical activities and health monitoring for pregnant women. Their framework consisted of only three sensors, a three-axis accelerometer, a three-axis gyroscope, and a temperature sensor, as well as a Raspberry Pi, same to [9], and a mobile phone, Figure 6.…”

“…As a result, a single wearable sensor module containing the three sensors mentioned above was employed, which was mounted at the wrist and connected to the raspberry pi through Bluetooth using Python-based BlueZ. Similarly, to [14], a GSM modem was used to store the phone numbers of registered gynecologists and caregivers, who would receive a message if the maternal women did not perform as expected.…”

First and foremost, I would like to thank my parents, my sister, and the rest of my family for always believing in me and telling me that I would be able to finish the thesis, even when I thought I couldn't.I'd also like to thank all of my college friends, my "Octajericos," who always tried to help me and believed in me and my abilities, as well as "Casa Carlos," who represent my home friends and colleagues who always supported me and put up with all of my stresses every day at home, making me laugh when I was down.Finally, I'd like to thank my supervisors, Carlos Coutinho and Daniel Calé, for making their time available to me, offering thoughts and suggestions, assisting me in organizing ideas, and being able to turn and describe all of my practical work into writing, allowing me to complete this thesis.Thank you to everyone I mentioned for their encouragement and trust; without them, it would have been very difficult for me to complete this chapter of my life. i Resumo É possível observar como as tecnologias de comunicação e informação avançaram a um ritmo bastante acelerado nos dias de hoje. A introdução e aparecimento da tecnologia "wearable" representa um aspeto que contribui para este progresso e tem o potencial de ser uma solução inovadora para os desafios dos cuidados de saúde, uma vez que pode ser utilizada para a prevenção e manutenção de doenças, tais como a monitorização física, bem como para a gestão de pacientes.Para abordar alguns dos desafios dos cuidados de saúde, esta tese de investigação propõe uma metodologia de investigação, questões de investigação, e hipóteses para o desenvolvimento de um sistema inteligente de monitorização da saúde com alertas e monitorização contínua utilizando wearable devices capazes de recolher dados biométricos de seres humanos.O conceito foi então provado pelo desenvolvimento de um protótipo utilizando wearable devices conectados a um microcontrolador, que transmite os seus dados através do Protocolo MQTT a um painel de instrumentos alimentado por o Node-RED que lida com a monitorização de métricas de saúde e onde toda a monitorização executada, e os alarmes gerados, podem ser visualizados em tempo real e depois entregues numa base de dados MongoDB para posterior análise e visualização.Para demonstrar a eficácia deste protótipo, este foi implementado no mundo real onde foram adquiridos vários resultados através da utilização de dois utilizadores distintos. Os resultados foram bastante favoráveis e conclusivos, demonstrando que o protótipo criado foi satisfatório no fornecimento de dados para apoiar as hipóteses e questões de investigação desenvolvidas.
