Abstract

It is already well known that there are numerous environmental and political reasons to move away from fossil fuels and towards alternative energy solutions. Solar energy has been regarded as an ideal alternative energy and has great potential for satisfying future energy demands. In this key-note lecture, it will be presented that the fundamentals of dye sensitized solar cells (DSSC) including history and background, energy harvesting cycle, principles of DSSC, and solar cell operation. The lecture then discusses the next generation technologies to improve the effic-iency of DSSC. Finally, this lecture introduces some research results performed by author with his graduate students. Dye-sensitized Solar Cells(DSSC) are a believable alternative to conventional silicon solar cells because of their ease to fabrication, low-cost compared with other photovoltaics and wide applications.

Wearable Obstacle Avoidance System Integrated with Conductive Yarns for Visually Impaired People

Prof. Vladan Koncar
University Lille North of France,
ENSAIT, GEMTEX F-59100, Roubaix, France

Abstract

The main objective of this study is to help blind or visually impaired people to navigate safely and quickly among obstacles and other hazards faced by blind pedestrians in indoor environment. Towards this objective, an innovative approach based on integration of electronic components onto textile structures was realized. By this way, a new wearable obstacle detection system, which can be worn as a garment that is flexible, lightweight and comfortable for the human body has been designed. The proposed smart clothing navigation system would become united part of visually impaired people’s. The smart clothing navigation system is an initial prototype system that combines garment with sensors, actuators, power supplies and a data processing unit.

Photovoltaics go Textile: Fundamental Considerations and Materials Aspects to Realize Dye-sensitized Solar Cells on Textile Electrodes

D. SCHLETTWEIN
Justus-Liebig-University Gießen, Institute of Applied Physics, Gießen, Germany

Textile-based photovoltaics are of interest for an independent energy supply for a number of textile- integrated electronic applications, mainly in medical and outdoor applications. Preparation of semiconductor films from precursor solutions represents the most promising approach because of good compatibility of the processes to a low thermal stability of textiles and to the need of a three- dimensional coating process.

Abstract

With the increasing of aging population in the world, healthcare and biomedical functions of textiles become more and more important. To meet the increasing demand in the society, textile biomedical engineering (TBE) aims to develop a holistic and integrative approach of designing and engineering devices to meet the biomedical and healthcare needs by providing various functions such as drug delivery, tissue engineering and artificial implants, temperature and pressure therapy, bioelectric/magnetic detection and stimulation for the health and recovery of human body. TBE is experimental in nature and needs extensive multi-disciplinary collaborations among the experts in medical professionals, physiologists and designers, scientists and engineers in textile and clothing industry. Design and engineer of textiles for biomedical applications involve the integration of the fundamental research in physical, chemical, mathematical, and computational sciences with the development of engineering principles with sound understanding on the relationship between clothing and human biology, medicine, behavior and health. Fundamental concepts need to be advanced together with creating new knowledge from molecules to body-textile systems, and developing innovative materials, devices, and apparel products for healthy lifestyles with the functions of comfort, protection, prevention, diagnosis, and treatment of disease and healthcare.

Nanofiber – Enhanced TexTILEs for Health and Protection

Prof. dr. Marian G. McCord
Director of Global Health Initiatives
Associate Professor
Textile Engineering, Chemistry, and Science Biomedical Engineering

Abstract

Novel nanofiber-enhanced textiles have been developed through electrospinning and plasma processing. The novel bioactive nanofibers feature multiple functionalities including: i) high barrier efficiency; ii) excellent detoxifying efficiency against toxic chemicals; and iii) antimicrobial activity against gram (+) and gram (-) microorganisms. The nanofibers were deposited on textile substrates to form novel layered composite systems. The adhesion between nanofiber layer and substrate textiles can be remarkably increased by both conventional and hybrid plasma treatment. The plasma-treated nanofibers showed excellent performance and durability in a peeling test, a Gelbo Flex test and an abrasion test. The nanofiber-enhanced textiles have shown promise for use in protective clothing and wound dressings. Continue reading Nanofiber – Enhanced TexTILEs for Health and Protection

The natural world around us provides excellent examples of functional systems built with a handful of materials. Throughout the millennia, nature has evolved to adapt and develop highly sophisticated methods to solve problems. The solutions found in nature include superhydrophobicity, self cleaning, self repair, energy conservation, drag reduction, dry adhesion, adaptive growth, and so on. There are numerous examples of functional surfaces, fibrous structures, structural colours, self-healing, thermal insulation, etc., that offer important lessons for the textile products of the future. This paper provides a general overview of the potential of bio-inspired textile structures by highlighting a few specific examples of pertinent, inherently sustainable biological systems.
