Abstract

Examines the seventeenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

Abstract

The need for textile-based antennas originates from the development of smart textile systems that emerged in the nineties. The aim is to increase the functionality of textiles, in most cases, clothing, by adding electronic systems. This allows the monitoring of physical (such as heart or respiration rate) as well as environmental (such as humidity or temperature) parameters through an embedded sensor network. The availability of micro electronics on the one hand, and new textile materials on the other, stimulates this evolution. The development of integratable textile-based sensors and flexible interconnections is continuously ongoing research. Also, wireless data transfer from the garment to a nearby base-station requires new developments, especially when the flexibility and comfort of the garment needs to be preserved. This paper gives a detailed overview on performed research and reveals the feasibility, design and manufacturing process of textile-based antennas for this off-body communication. The antennas are low profile, breathable, light-weight and simple in structure which make them suitable to be unobtrusively embedded in apparel and provide flexibility and satisfactory performance.

Abstract

Purpose

This research investigated the feasibility of using an inductively coupled antenna as the basis of applying a systems approach to smart clothing. In order to simulate real-life situations, the impact of the distortions and relative displacement of different fabric layers (with affixed antennas) on the signal quality was assessed. The paper aims to discuss these issues.

Design/methodology/approach

A spiral antenna was printed on different fabric substrates. Obstructive conditions of the inductively coupled fabric layers were investigated to find out how much influence these conditions had on transmission performance. Reflected signals and transmitted signals were observed, while fabric antennas were subjected to displacement (distance and dislocation) or deformation (stretching and bending). The threshold of physical obstacles was estimated based on statistical analyses.

Findings

The limits of physical conditions that enable proper wireless transmission were estimated up to ∼2 cm for both distance and dislocation, and ∼0.24 K for bending deformation. The antenna performance remained within an acceptable level of 20 percent transmission up to 10 percent fabric stretch. Based on well-established performance metrics used in clothing environment on the body, which employs 2-5 cm of ease, the results imply that the inductively coupled antennas may be suitable for use in smart clothing.

Originality/value

This research demonstrates that the use of inductively coupled antennas on multiple clothing layers could offer the basis of a new “wireless” system approach to smart clothing. This would not only result in performance benefits, but would also significantly improve the aesthetics of smart clothing which should result in new markets for such products.

Abstract

After technical textiles and functional textiles, smart textiles came into force a few years back. The term “smart textiles” covers a broad range. The application possibilities are only limited by our imagination and creativity. Hence it is not simple for the readers of the many articles that have been published to distinguish where reality ends and where fiction begins. In this paper, it is further explored what smart textiles precisely mean. In a second part, an analysis is made of the possibilities, the state of affairs and the need for further research, including research in the Department of Textiles at the Ghent University (Belgium).

Abstract

Purpose

The purpose of this paper is to exploit a database of pre-existing designs to accelerate parametric optimization of antenna structures is investigated.

Design/methodology/approach

The usefulness of pre-existing designs for rapid design of antennas is investigated. The proposed approach exploits the database existing antenna base designs to determine a good starting point for structure optimization and its response sensitivities. The considered method is suitable for handling computationally expensive models, which are evaluated using full-wave electromagnetic (EM) simulations. Numerical case studies are provided demonstrating the feasibility of the framework for the design of real-world structures.

Findings

The use of pre-existing designs enables rapid identification of a good starting point for antenna optimization and speeds-up estimation of the structure response sensitivities. The base designs can be arranged into subsets (simplexes) in the objective space and used to represent the target vector, i.e. the starting point for structure design. The base closest base point w.r.t. the initial design can be used to initialize Jacobian for local optimization. Moreover, local optimization costs can be reduced through the use of Broyden formula for Jacobian updates in consecutive iterations.

Research limitations/implications

The study investigates the possibility of reusing pre-existing designs for the acceleration of antenna optimization. The proposed technique enables the identification of a good starting point and reduces the number of expensive EM simulations required to obtain the final design.

Originality/value

The proposed design framework proved to be useful for the identification of good initial design and rapid optimization of modern antennas. Identification of the starting point for the design of such structures is extremely challenging when using conventional methods involving parametric studies or repetitive local optimizations. The presented methodology proved to be a useful design and geometry scaling tool when previously obtained designs are available for the same antenna structure.
