Firstly, the multiplication of terminals, linked to the activity of smartphones and computers, is leading to a<strong> rapid growth in electricity consumption<\/strong> equivalent today to 15 % of world consumption. Secondly, current technology has reached its <strong>physical limits<\/strong>with the end of the <em>Moore's Law<\/em> which predicted that the power of microprocessors would double every eighteen months. With the addition of the energy constraint, the architecture of the information processing system had to be completely overhauled, and Alain Cappy's conversion was an obvious choice:<\/p>\n<blockquote>\n<p>\"For a long time, I had been working on ultra-fast devices that consumed a lot of power and could not be significantly reduced. It was while I was looking for more energy-efficient architectures that I got the idea of looking at information processing in the brain, and therefore at the properties of neurons. I was very surprised to find that the physics of how neurons work was similar to that of the components (field effect transistors) that I had always worked on. We can even draw a formal analogy between the insulating membrane that surrounds the neuron and the insulator that forms the basis of the transistor effect in semiconductor devices\".<\/p>\n<\/blockquote>\n<div id=\"attachment_42659\" style=\"width: 173px\" class=\"wp-caption alignleft\"><a href=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2020\/10\/Neurone-artificiel.jpg\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-42659\" class=\"wp-image-42659\" src=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2020\/10\/Neurone-artificiel-300x225.jpg\" alt=\"\" width=\"163\" height=\"122\" srcset=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2020\/10\/Neurone-artificiel-300x225.jpg 300w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2020\/10\/Neurone-artificiel.jpg 600w\" sizes=\"auto, (max-width: 163px) 100vw, 163px\" \/><\/a><p id=\"caption-attachment-42659\" class=\"wp-caption-text\">Integrated circuit emulating artificial neurons<\/p><\/div>\n<p>Moving into familiar territory, and surrounding himself with a team of researchers, he quickly got down to the nitty-gritty. But we had to go beyond the biological model. <strong>technology isn't about copying, it's about trying to do things differently and better<\/strong> \u00bb.<br \/>\nThat's how the team made <strong>artificial neurons<\/strong> which are energetically 1000 times more efficient than a living neuron, i.e. they <strong>use around 1000 times less energy to create the same electrical impulse<\/strong>. The reason is simple: an electronic neuron is 1000 times smaller than a living neuron, so the ratio of sizes determines the ratio of energies.<br \/>\nAlain Cappy opened <strong>two lines of research<\/strong> in the field of bioinspired architectures, which is now a major area of research at IEMN and IRCICA. One, with Fran\u00e7ois Danneville and Christophe Loyez, aims to <strong>be inspired by the architecture of the brain<\/strong>to create intelligent and efficient vision systems. The other way, to <strong>therapeutic aim<\/strong>with Virginie Hoel, is working to make living neurons interact with artificial neurons to form implants, in order to treat neurodegenerative diseases. The <strong>start up Axorus<\/strong>created in 2019 and dedicated to <strong>treatment of AMD <\/strong>(age-related macular degeneration), aims to promote this research.<\/p>\n<p><a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/book\/10.1002\/9781119721802\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/onlinelibrary.wiley.com\/doi\/book\/10.1002\/9781119721802<\/a><\/p>\n<\/div><\/section><\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":2,"featured_media":43730,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[36,30],"tags":[],"class_list":["post-42590","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-articles-temporaires","category-breves"],"_links":{"self":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/42590","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/comments?post=42590"}],"version-history":[{"count":0,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/42590\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media\/43730"}],"wp:attachment":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media?parent=42590"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/categories?post=42590"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/tags?post=42590"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
