Development of sensor design for smart kinesiotape for future sensing applications in motion capturing
The “CENTRE FOR TACTILE INTERNET WITH HUMAN-IN-THE-LOOP (CeTI)” is a Cluster of
Exellence that, from an textile point of view, deals with the development and invention
concerning smart devices [1]. These can be used in many fields e.g. industry 4.0, medicine
and skill leaning. Currently expensive, tender and large, stationary camera systems are
necessary to capture human motions for various applications. The usage of textile substrates
with implemented sensory units gives high potential for body-near motion capturing. Smart
textiles gain more and more interest in the field of sports [2] and health monitoring. The
avoidance of personal injuries due to the incorrect execution of movements is one main target
to reach with smart textiles in healthcare and sports. The aim of the contribution is the
investigation of characteristics using electrically conductive (EC) yarns implemented in
woven textiles as future smart textiles for close up motion capturing
The role of light in the city
Architektura definiowana jako gra brył w świetle staje się tworem
transcendentalnym, podlegającym nieustannym zmianom, wykracza poza
swoją z góry zdefiniowaną formę, tworząc nieskończone możliwości
odczytywania jej na nowo. Światło wpływa na postrzeganie przestrzeni
miejskiej, nasze samopoczucie, poczucie bezpieczeństwa, klimat oraz kontekst
danego otoczenia.
Najpierw zostanie przedstawiona rola światła w historii kształtowania się miast
na przestrzeni wieków z perspektywy urbanistycznej. Następnie omówiona
zostanie rola światła we współczesnych miastach. Ma ono znaczenie dla
funkcjonowania tkanki miejskiej; rozpoczynając od rytmu życia mieszkańców
po wszelkie oryginalne przejawy kreatywności i wykorzystywania zastanego
środowiska do tworzenia wystąpień o charakterze performatywnym.
Projektując strukturę urbanistyczną, nie możemy kierować się jedynie
aspektami ważnymi dla człowieka, ponieważ czynniki naturalne w znacznym
stopniu wpływają na postrzeganie przestrzeni. Względy środowiskowe,
wspólne naszemu organizmowi oraz florze i faunie, skonfrontowane ze
zrównoważonym projektowaniem, nie dają nam jednoznacznego rozwiązania,
jak powinniśmy kształtować oświetlenie miejskie. Pod koniec zostanie podjęta
refleksja, z perspektywy architektonicznej, jakie rozwiązania byłyby właściwe
w kontekstach istotnych dla tematu perspektyw – środowiskowej,
urbanistycznej oraz filozoficznej.Architecture is defined as the masterly, correct, and magnificent play
of volumes brought together in light – it becomes a transcendental creation,
subject to constant changes, it goes beyond its predefined form, creating an
infinite number of ways to read it anew. The perception of urban space, our
well-being, sense of security, ambience, and the context of an environment
are all influenced by light. First, the role of light in the history of city shaping
over the centuries will be presented from an urban perspective. The
importance of light in modern cities will then be discussed. It is critical for the
functioning of the urban tissue, beginning with the rhythm of life of the
inhabitants and continuing with all original manifestations of creativity and use
of the existing environment to create performative performances. When
designing an urban structure, we cannot only consider aspects that are
important to humans, because natural factors have a significant impact on
how people perceive space. When confronted with sustainable design,
environmental considerations common to our organism (soma) and flora and
fauna do not provide a clear solution on how we should design urban lighting.
In conclusion, from an architectural standpoint, what solutions would be
appropriate in the contexts relevant to the most important perspectives –
environmental, urban, and philosophical – will be considered
The effect of 3D weft-knitted fabric composition on puncture, tear, and air permeability
This study investigates the influence of 3D weft-knitted fabric fibre composition on the risk of puncture
and tear and evaluates the air permeability of these protective knits. For this purpose, different 3D weftknitted
fabrics, consisting of outer (protective), binding, and inner (suitable for contact with skin) layers,
were produced on an E20 circular weft-knitting machine using different quantities of high molecular
weight polyethylene (HMWPE) (from 49% to 24%) and inorganic yarns (from 0% to 23%) in the outer
layer while the quantity of polyester in the inner layer and polyamide in the binding layer was kept the
same. The puncture and tear resistance tests were conducted to determine the resistance of the 3D weftknitted
fabrics to mechanical risks. The air permeability test was performed to assess the comfort
properties of the protective 3D weft-knitted fabrics. According to the puncture and tear resistance testing
results, it was determined that the highest HMWPE percentage content in the outer layer of 3D weftknitted
fabric provided the highest resistance to these mechanical risks. Based on the air permeability
test results, it was found that knit with the highest inorganic yarns content in the outer layer achieved
the highest air permeability value
Coating functionalized with silicon carbide for cut-resistant protective glove
Workers’ hands are at the highest risk of being affected by harmful factors in the work environment and
upper limb injury is the most widespread type of workplace accident occurring during the performance
of manual tasks. The protective properties of glove materials may be improved by continuous or spot
coating [1–2] with polymeric materials such as poly(vinyl chloride), polyurethane, silicone, and natural
or nitrile rubber [3–6]. The objective of the present work was to evaluate the effects of different size of
particles added to a polymer material applied onto a textile carrier on the cut resistance of the resulting
material. Knitted aramid textile samples were coated in laboratory conditions using a polymer paste that
was functionalized with silicon carbide (SiC) reinforcing particles of three different size fractions. On
the basis of the research it was found that the smallest size of SiC particles had the greatest effect on
increasing cut resistance
Technological design of jacquard fabric and their functionalization
Functionalization of fabrics allows us to influence the physical-mechanical properties by using special
yarns that improve fabric's properties, such as elasticity [1,2], thermal regulation [3,4], protection against
ultraviolet (UV) rays [5–7], etc. In addition, from a design point of view, the shape and size of the
pattern, its frequency and area distribution are also important, not only as a visual effect, but also in
terms of the above-mentioned properties [8–10]. The aim of the study was to determine how different
weft yarns, the size of the pattern and weave affect the final properties of the jacquard fabric.
Six jacquard fabrics were woven on the same warp with two different weft yarns (cotton, Lyocell Clima)
in two different patterns and two groups of double twill weaves (stiched and unstiched). The results
show that fabrics made of cotton have poorer mechanical properties and lower permeability than fabrics
with Lyocell Clima weft. Double unstitched fabrics generally have poorer mechanical properties and
UV protection factors (UPF), but better air permeability values. A statistically significant influence of
the raw material was shown for thickness, mass, thermal conductivity, tensile strength and, in the case
of the size pattern and weave, for air permeability, breaking and tear strength
Effect of footwear material on the plantar pressure of diabetic foot
This paper examines the effect of sole material on the plantar pressure for different skin aging conditions of a diabetic foot. A fully parametric finite element model, based on a 3D bio-model, was developed, and used to evaluate the effect of various combinations of sole materials and skin stiffness on the developed plantar pressure distribution for three main gait phases. The results reveal the significant effect of sole on the reduction of plantar pressure and how it varies for different skin aging conditions and gait phase
Late-Scholastic Economics and Classical Liberal Thought
Late-scholastic economics is still the most underrated discipline in the history
of economic thought. In contrast, its contribution to the development of economics
and the way of thinking about economic matters is worthy of attention.
This article presents the economic thought of the late Spanish scholastics proving
that with their concepts on economic affairs, they preceded the advent
of many economic theories by centuries and even avoided some of the mistakes
made by liberal thinkers. In the period when medieval scholars formulated
their concepts, economic life differed significantly from modern economic
reality. Nevertheless, many of their considerations concern issues that are still
topical today and considered free-market ideas
Numerical simulation and experimental study of trapezoidal tear of triaxial woven fabric
The tear damage of triaxial woven fabric (TWF) are investigated by numerical simulation method and
experiment method to study the tear properties of samples with pre-cut in different directions. It is
analysed that the changing law of tear load and the characteristics of tear failure during tear process.
The results indicate that the tear load-displacement curve can be divided into low modulus region, high
modulus region and shock region, which are related to initial stage, pre-cut opening stage and tear
opening expansion stage the tear process of TWF. When the pre-cut is parallel to the yarn, samples have higher tear load and larger tear starting position
