[article]  inCHEMICAL FIBERS INTERNATIONAL > Vol. 69, N° 1 (03/2019) . - p. 46-48 Titre : Electrospun multifunctional nanofiber nonwovens for bio-inspired computers Type de document : texte imprimé Auteurs : Christoph Döpke, Auteur ; Timo Grothe, Auteur ; Michaela Klöcker, Auteur ; Andrea Ehrmann, Auteur ; Tomasz Blachowicz, Auteur ; Pawel Steblinski, Auteur Année de publication : 2019 Article en page(s) : p. 46-48 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Electrofilature Magnétisme Matériaux bio-inspirés Nanofibres Nontissés Index. 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.

The edge length of the extracted area is 800 nm. The magnetization is shown in red when pointing to the right - Fig. 4 : Generation and movement of domain walls by a bent nanofiber. In the red areas, the magnetization is oriented to the righe, in the green areas perpendicular to this axis En ligne : https://drive.google.com/file/d/19B7GcXUSLXa3VUCamPKttBdaHqRFAepw/view?usp=drive [...] Format de la ressource électronique : Pdf Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=32210 [article]
