Title:Fiber Optic Sensors for e-Health Architectures
Objectives (recommended length: 2000-3000 char):
The proposed research plan focuses on the development of optical sensors for the next generation of e-Health monitoring systems, through the design of a network of fiber optic sensors integrated in equipment to be used by patients, able to monitor their health conditions through the observation of physiological parameters. Thus, vulnerable groups such as patients with diabetes, cardiovascular disease, gait deficiencies / injuries, and even people with a high mobility disability (bedridden people) may have access to instant help with the possibility of a constant physician/caregiver/patient interaction through an e-Health connection.
Sedentary life such as the aging of the population is associated with the reduction of capacity or even locomotive incapacity of citizens. In this sense there is a need to find effective solutions to reduce costs and improve the quality of life of the population. Fortunately, recent developments in electronics and communication networks have redirected the interest of scientific communities towards applications aimed at improving the quality of life of the population. This has led to great interest in areas such as Internet of Things (IoT), Smart City and Data Science, and in particular in the e-Health topic.
In the same context, it is also intended to develop an equipment capable of monitoring the walking pattern and the health conditions of the patient during rehabilitation/diagnosis in rehabilitation platforms (static and dynamic), through the incorporation of a network of fiber optic sensors. The prior art will also be used to develop flexible platforms capable of sensing the pressure exerted by the body of a bedridden person in order to continuously monitor their position as well as other relevant physiological parameters. The fiber optic sensor network will primarily be based on Fiber Bragg Gratings (FBG) technology, but other types of fiber optic solutions that prove to be efficient and cost-effective will also be tested. This sensor network will be integrated with a mobile interrogation monitoring interface and control software.
Despite the existence of insoles and platforms with plantar and vertical pressure sensors in the market, the solutions presented are based on the use of electric/resistive sensors, susceptible to electromagnetic interference, or to failures and accidents in their contact with humid environments, such as, sometimes, the human body.
This proposal is supposed to provide an opportunity to the doctoral student for developing a research project in a business environment, training research work at advanced research labs of a reputed company with long experience working on the eHealth market. Simultaneously, it is expected to contribute significantly to solve specific technological problems identified by the company.
Framework (recommended length: 500-2000 char):
The photonic technologies have acquired a vital importance in the development of solutions for monitoring. In recent decades there has been a growing interest in research in this area resulting in the development of new techniques, instruments and sensors. In recent decades, the fiber optic sensors have proven to be a promising technology in various fields of application. Being durable, stable, insensitive to electromagnetic interference, resistant to corrosion, with minimal aesthetic intrusion, electric isolation and low size, they are particularly interesting on the monitoring of structures under high-risk, aggressive or explosive environments, such as hydroelectric dams, nuclear power plants, oil or gas drilling, high sea or submerged structures, etc., where the optical fiber technology offers massive advantages over traditional electronic sensors. Further advantages of using such technology include the no need for electrical power on the measurement site which can be located kilometers from the acquisition site (only an optical fiber connection is necessary) and the multiplexing capacity, allowing to place dozens of sensors on the same fiber optic cable, drastically reducing cabling weight, size and installation costs.
The proposed work plan fits in the activity of the research group "Optics and Optoelectronics" of the I3N-Aveiro, with long time experience on the development and prototyping innovative optical fiber sensors, contributing for its expansion and development. The host facilities are very well equipped, with recent femtosecond and Nd:YAG laser platforms, both able to produce customized FBG sensors.
PLUX has the proper knowhow and long experience about to produce, characterize and test biomedical for commercial use, being the perfect location for the proper implementation several important tasks.
Moreover, although some tasks are mostly completed at one location, the support of the other institution/company with be provided during the full programme.
