Using Radio Frequency Identification Technology In Healthcare

In the healthcare industry, medical treatment can be a matter of life and death, so that any mistakes may cause irreversible consequences. As hospitals have sought to reduce these types of errors, Radio Frequency Identification Technology (RFID) has become a solution in the healthcare industry to address these problems. Since 2005, RFID has generated a lot of interest in healthcare to make simpler the identification process for tracking and managing medical resources to improve their use and to reduce the need for future costs for purchasing duplicate equipment. There are rising concerns linked to the privacy and security issues, when RFID tags are used for tracking items carried by people. A tag by its design will respond to a reader\u27s query without the owner\u27s consent and without the owner even noticing it. When RFID tags contain patients\u27 personal data and medical history, they have to be protected to avoid any leaking of privacy-sensitive information. To address these concerns, we propose an Intelligent RFID System which is a RFID card system that embeds smart tags in insurance cards, medical charts, and medical bracelets to store medical information. Patient data is sent to the insurance providers by way of a clearinghouse that translates the information from the healthcare facility into a format that the insurance company can process. To ensure data protection, an additional security layer was added to secure the communication between the tags and the readers. This security layer will allow only authorized readers to poll tags for the patient\u27s medical tags and prevent unauthorized access to tag data. It will simplify the maintenance and transfer of patient data in a secure, feasible and cost effective way

Visible Light Communications for Industrial Applications—Challenges and Potentials

Visible Light Communication (VLC) is a short-range optical wireless communication technology that has been gaining attention due to its potential to offload heavy data traffic from the congested radio wireless spectrum. At the same time, wireless communications are becoming crucial to smart manufacturing within the scope of Industry 4.0. Industry 4.0 is a developing trend of high-speed data exchange in automation for manufacturing technologies and is referred to as the fourth industrial revolution. This trend requires fast, reliable, low-latency, and cost-effective data transmissions with fast synchronizations to ensure smooth operations for various processes. VLC is capable of providing reliable, low-latency, and secure connections that do not penetrate walls and is immune to electromagnetic interference. As such, this paper aims to show the potential of VLC for industrial wireless applications by examining the latest research work in VLC systems. This work also highlights and classifies challenges that might arise with the applicability of VLC and visible light positioning (VLP) systems in these settings. Given the previous work performed in these areas, and the major ongoing experimental projects looking into the use of VLC systems for industrial applications, the use of VLC and VLP systems for industrial applications shows promising potential

This thesis is the result of a compendium of publications on this topic. First, as a result of the analysis of the state of art, a systematic review entitled 'Wearable textile UHF-RFID sensors: A systematic review' has been published. The thesis aims to improve research on UHF-RFID textile-based sensor technology. Thanks to the analysis of the state of art, three novel research objectives have been set that are worth exploring. The first is to study novel detection functions for textile UHF-RFID based sensor technology; the second is to find a connection/interface solution between textile antennas and integrated circuit (IC) chips and the third is to reduce the costs of such technology to promote future commercial applications. To contextualize the thesis, it includes the necessary theoretical fundamentals and the manufacturing and characterization methods used during it. As a result of the work derived from the first objective, a scientific article entitled “Textile UHF-RFID Antenna Sensor for Measurements of Sucrose Solutions in Different Levels of Concentration” has been published. In this work, a textile UHF-RFID tag with two detection positions is proposed for sucrose solution measurements. The two detection positions with the different detection functions show good performance and can offer two options for future full applications. In addition, another scientific article entitled “ Textile UHF-RFID Antenna Embroidered on Surgical Masks for Future Textile Sensing Applications” has been published to support the first objective. The inspiration for this work came from the current pandemic situation. This work develops three progressive designs of textile UHF-RFID antennas over surgical masks due to the current global epidemic situation. Reliability testing demonstrated that the proposed designs can be used for human healthcare focused applications. As a result of the second objective, a research article entitled 'Experimental Comparison of Three Electro-textile Interfaces for Textile UHF-RFID Tags on Clothes' has been published. This work proposes three electro-textile interfaces integrated with the corresponding textile UHF-RFID antennas and provides the chip-textile connection solutions (through sewing, push buttons and insertion). As a result of this objective, an electro-textile interconnect system has been proposed together with its electrical model, which allows the correct adaptation of impedances between the RFID antennas and the integrated circuit. It is worth noting that the mixed-use feasibility of the proposed electro-textile interfaces and the designed textile UHF-RFID antennas has been verified, reducing the cost in the design procedure in applications where the read range requirements of the order of 1 meter. The third objective has been achieved and exposed by a scientific article entitled 'Electro-textile UHF-RFID Compression Sensor for Health-caring Applications'. It proposes a single UHF-RFID based compression textile sensor that can be used simultaneously in two different healthcare application scenarios, which directly impacts on cost reduction.La identificación por radiofrecuencia sobre substratos textiles de ultra alta frecuencia (UHF-RFID) con capacidad de medida es una tecnología prometedora para desarrollar nuevas aplicaciones en el campo de la salud y el Internet de las cosas (IOT), debido a la masiva utilización de los tejidos y a la madurez tecnológica de las técnicas de bordado.

ST focuses on developing sensors, sensory systems, or smart materials that monitor a wide variety of materials’ properties aiming to create smart structures and smart materials, using Embedded Sensors (ESs), and enabling continuous and permanent measurements of their structural integrity. The integration of ESs is limited to the processing technology used to embed the sensor due to its high-temperature sensitivity and the possibility of damage during its insertion into the structure. In addition, the technological process selection is dependent on the base material’s composition, which comprises either metallic or composite parts. The selection of smart sensors or the technology underlying them is fundamental to the monitoring mode. This paper presents a critical review of the fundaments and applications of sensing technologies for SHM systems employing ESs, focusing on their actual developments and innovation, as well as analysing the challenges that these technologies present, in order to build a path that allows for a connected world through distributed measurement systems.publishersversionpublishe

Towards sustainable manufacturing: information sharing framework of end-of-life immediate return

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel UniversityWe live in an economy that is exhausting natural resources. With the improvement of the world economy and the rapid development of its electrical industry, electrical and electronic products are continually upgraded, electrical and electronic equipment waste (WEEE, or e-waste) which endangers human health is increasing rapidly. To reintegrate economy within ecological limits, it is to increase social and environmental sustainability. As businesses are endowed with resources and capabilities to drive the change, they also have valuable information that can positively impact production and consumption systems. Based on this, this research is intended to explore Business-to-Consumer (B2C) communication in communicating immediate post-consumption (end-of-life) return in the closed-loop supply chain. The communication is based on information sharing activity where businesses consider including specific end-of-life return information. The purpose of this research is to explore information content and message framing that could be used to present end-of-life product return information, and how it affects consumers’ attitude towards return information and consumers’ immediate return intention based on formative research suggested by social marketing theory. The proposed framework visualizes the relationship of proposed types of information and information presentation towards consumers’ immediate return attitude, as well as environmental motivation and environmental knowledge as the moderators in consumers’ segmentation. This exploratory research is intended to support qualitative and quantitative studies which aim to clearly (a) justify that time and quality of return should be included in product return information, (b) understand the effect of information presentation (message framing) on consumers’ immediate return intention of used electric and electronic appliances, (c) investigate how individual’s environmental motivation and knowledge influence their way of processing immediate return information
