“…Weaving has been the major technique to produce textile-integrated polymer optical fibers [20,59,60]. In weaving, two orthogonal sets of yarns called warp (end) and weft (pick or filling) are interlaced on a weaving loom to form a fabric as illustrated in figure 5 [61,62].…”

With ever growing interest in far-reaching solutions for pervasive healthcare and medicine, polymer optical fibers have been rendered into textile forms. Having both fiber-optic functionalities and traditional fabric-like comfort, textile-integrated polymer optical fibers have been advocated to remove the technical barriers for long-term uninterrupted health monitoring and treatment. In this context, this paper spotlights and reviews the recently developed textile-integrated polymer optical fibers in conjunction with fabrication techniques, applications in long-term continuous health monitoring and treatment, and future perspectives in the vision of mobile health (mHealth), as well as the introductory basics of polymer optical fibers. It is designed to serve as a topical guidepost for scientists and engineers on this highly interdisciplinary and rapidly growing topic.

“…For a successful treatment, a special pattern (patent WO 2012098488 A2) composed of three satin weaves was designed to obtain the same amount of bending, thus a homogenous light distribution on the whole length of the fabric when it is connected to sources from both ends [36][37][38]. With this new pattern a homogenous light distribution was aimed for a successful PDT.…”

A successful photodynamic therapy (PDT) requires a specific photosensitizer, oxygen and light of a specific wavelength and power. Today photodynamic therapy (PDT) is administered to patients with light-emitting diode (LED) panels. These panels deliver a non-uniform light distribution on the human body parts, as the complex human anatomy is not a flat surface (head vertex, hand, shoulder, etc.). For an efficient photodynamic therapy (PDT), a light-emitting fabric (LEF) was woven from plastic optical fibers (POF) aiming at the treatment of dermatologic diseases such as actinic keratosis (AK). Plastic optical fibers (POF) (Toray, PGR-FB250) have been woven in textile in order to create macro-bendings, and thus emit out the injected light directly to the skin. The light intensity and light-emitting homogeneity of the LEF were improved thanks to Doehlert Experimental Design. During the treatment with PDT, the photosensitizers were activated in the cancerous cells. These cells may be visualized, as they show a characteristic fluorescence under UV light, which is called fluorescence diagnosis (FD). Therefore, it is proposed to modify the developed LEF for PDT to measure the fluorescence amount. For this aim, a part of POFs was cut out to observe the quantity of light that could be collected while the LEF was connected to a light source. The first prototypes showed the possibility of the illumination with the same LEF without losing the efficiency but also imaging the collected light.

“…The combination of textiles and electrical components is a novel research field, and the resulting products, called "e-textiles", have been commonly used in light therapy [1]. Since electrical components broke the limit in terms of their size, e-textiles have had more diverse applications, such as monitoring physiological functions [2] and medical therapy [3].…”

ABSTRACT The combination of functional electrical products improves the value of textiles, including measurement, detection, and communication. These added values, however, have a negative influence on comfort and consumer acceptance. This study proposes using a knitting technique and conceals the circuit that connects electrical components inside the textiles, thereby ensuring satisfactory comfort and mechanical properties. The pattern designed using a crochet machine is applied to the preparation of conductive elastic knits. During the process, different numbers and types of conductive yarns are incorporated. The stiffness, tensile strength, elastic response rate, air permeability, and electrical resistance of conductive elastic knits are evaluated. The rigidity and electrical resistance test results show that increasing the numbers of conductive yarns results in a lower electrical resistance, as well as a rugged knit surface and exposure of the yarns. Moreover, increasing the numbers of conductive yarns does not pertain to the physical properties of elastic knits, according to the results of air permeability, tensile strength, and elastic recovery tests.
