NontissésIndex. décimale : 677 Textiles Résumé : Today's computers are based on the so-called von Neumann architecture — processor and memory are separated. For each arithmetic operation, data has to be transported back and forth between these two locations, which costs time and is referred to as the von Neumann bottleneck. In many cases, a bio-inspired architecture would be more efficient that is more like the human brain, where data is processed, stored, and transported within closely spaced small regions and between these areas. In a current project, funded by the Volkswagen Foundation under the funding line "Experiment !", a completely new approach is followed to create hardware for this so-called neuromorphic computing. While other research groups primarily use magnetic tunneling elements and similar modem devices to develop novel bioinspired computer structures, this project is based on a textile technology electrospinning.

CotonLe coton est une fibre végétale qui entoure les graines des cotonniers "véritables"(Gossypium sp.), un arbuste de la famille des Malvacées. Cette fibre est généralement transformée en fil qui est tissé pour fabriquer des tissus. Le coton est la plus importante des fibres naturelles produites dans le monde. Depuis le XIXe siècle, il constitue, grâce aux progrès de l'industrialisation et de l'agronomie, la première fibre textile du monde (près de la moitié de la consommation mondiale de fibres textiles).

Textiles et tissus -- Propriétés mécaniquesIndex. décimale : 677.4 Textiles artificiels Résumé : Fabric glues are often used for small repairs or in order to join 2 textile materials. In the area of smart textiles, they can be used to protect small electronic devices separating from textile substrates, e.g. caused by critical mechanical loading or by washing. This article deals with the role of gluing as a strain relief for the soldering points of SMD components. Different glued connections are investigated using separating force tests as well as Martindale tests. Note de contenu : - Fabric glues
