This article addresses the design, development, and evaluation of T-shirt prototypes that embed novel textile sensors for the capture of cardio and respiratory signals. The sensors are connected through textile interconnects to either an embedded custom-designed data acquisition and transmission unit or to snap fastener terminals for connection to external monitoring devices. The performance of the T-shirt prototype is evaluated in terms of signal-to-noise ratio amplitude and signal interference caused by baseline wander and motion artefacts, through laboratory tests with subjects in standing and walking conditions. Performance tests were also conducted in a hospital environment using a T-shirt prototype connected to a commercial three-channel Holter monitoring device. The textile sensors and interconnects were realized with the assistance of an industrial six-needle digital embroidery tool and their resistance to wear addressed with normalized tests of laundering and abrasion. The performance of these wearable systems is discussed, and pathways and methods for their optimization are highlighted.

In this article we present the design and development of T-Shirt prototypes that embed novel textile sensors for the capture of cardio and respiratory signals. The sensors are connected through textile interconnects to either an embedded custom designed data acquisition and transmission unit or to snap fastener terminals for connection to external monitoring devices. Prototypes with diverse approaches of integration are presented. The performance of the wearable systems is addressed in terms of signal-to-noise ratio amplitude and signal interference caused by baseline wander and motion artifacts, through laboratorial tests with subjects in standing and walking conditions. Performance tests were also conducted in Hospital environment using a T-Shirt prototype connected to a commercial 3-channel Holter monitoring device. The textile sensors and interconnects were realized with the assistance of an industrial 6-needle digital embroidery tool and their resistance to wear addressed with normalized tests of laundering and abrasion. The main aspects of the system´s design leading to major improvements and failure factors are discussed. Pathways and methods for the overall system´s optimization are highlighted.

In this article, plain weave fabrics of polyester were functionalized by means of a polymeric coating synthesized for high conductivity, using the vapor phase polymerization method. The method is considerably more efficient and sustainable than traditional wet methods and has been previously applied to synthesize poly(3, 4-ethylenedioxythiophene) in yarns and fabrics, using oxidant agents with organic solvents. In this article, aqueous oxidant solutions were used in addition to those based in ethanol, providing textile substrates with high electrical conductance. The effect of the concentration of the oxidant solution on the electrical and mechanical characteristics of the samples was investigated and correlated to their morphology, analyzed by electron microscopy imaging. A strong decrease of the sheet resistivity of the samples with the concentration of oxidant increase was obtained, while the fabrics’ original mechanical tenacity remained unchanged. The sheet resistivity of the samples could be further decreased by a factor of 5 by the application of multiple polymerization layers and was a function of the conjugated polymer content. The effect of washing/drying cycles on the electrical conductance of the samples is presented. The electrical and mechanical characteristics obtained have potential for smart textile applications such as electromagnetic shielding and physiological sensing.

Materials and processes play an increasingly significant role in the development of new fashion products and can significantly affect product sustainability and longevity. These aspects, like many others, are part of the numerous issues associated with sustainability [1, 2]. The Fashion ecosystem has a high impact on society and the environment. Sustainability is an important issue for the textile and clothing industry associated with the different stages of the product life cycle and their impacts. The skills of specialists in fashion product development (FPD) and respective training will have to evolve towards increased knowledge of materials and processes; however, the academy is not keeping up with these changes that go along with the rapid transformation of the industry. There is a need for new competence acquisition models that are tailored to the present-day requirements. The objective of this investigation concerns the use and validation of a set of methodologies for the acquisition of skills by students, which allows for the development of sustainable fashion products for the market. Active methodologies that are being used, include workshops, competitions, industry partnerships, and PD in the context of companies and academy, and using trainers with experience in the industry. It concludes a progress in the knowledge of sustainable materials and processes combined with motivation.

Purpose: – Considering that the human body is undeniable a fashion space, the purpose of this paper is to highlight the importance of design and material choice in the relationship between clothing and accessories, namely, bags, for the fashion consumer. Design/methodology/approach: – Initially the paper provides a historical framing of the use of materials in bags and its relation with clothing. Then, are described the characteristics of materials and how the human body relates to them, specifically how the sense of touch plays a decisive role in materials choice. Thus a natural fiber-based fabric as wool fabric is presented as a choice for some brands in the development of fashion accessories. Findings: – It was found that there are an immense variety of materials that can be used in bags creation, and the use of them has changed over the years, influenced by social and economic conditions, fashion trends, and by technology evolutions in the production of fibers and composites. Taking in consideration that there is a long history of use of woven fabrics with natural fibers and a growing demand for sustainable and organic products, the use of wool natural fabrics in the production of bags were presented as a following road to the fashion industry. Originality/value: – Since the relationship between materials used in apparel and fashion accessories is an area barely documented, this paper contributes to underline the possibility to exceed conventional design barriers and develop innovative and creative wool products pleasant for the human body as a fashion space.
