Firstly, the multiplication of terminals, linked to the activity of smartphones and computers, is leading to a <strong>rapid growth in power consumption<\/strong>, which is now equivalent to 15% of global consumption. Secondly, current technology has reached its <strong>physical limits<\/strong>, with the end of Moore\u2019s Law, which predicted a doubling of microprocessor power every eighteen months. Adding the energy constraint, it was therefore necessary to completely revise the architecture of the information processing system, and Alain Cappy\u2019s conversion became obvious :<\/p>\n<blockquote>\n<p>\u00ab\u00a0I had been working for a long time on ultra-fast but high-consumption devices whose consumption cannot be significantly reduced. It was while looking for more energy efficient architectures that the idea came to me to look at information processing in the brain and therefore at the properties of neurons. I was surprised to find that the physics of neurons was similar to that of the components (field effect transistors) that I had been working on since the beginning. One can even make a formal analogy between the insulating membrane that surrounds the neuron and the insulator at the base of the transistor effect in semiconductor devices. \u00bb<\/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 forward on familiar ground, and surrounding himself with a team of researchers, he quickly went into detail. But it was necessary to go beyond the biological model: <strong>\u00ab\u00a0technology is not copying but rather trying to do things differently and better\u00a0\u00bb.<\/strong><br \/>\nThat\u2019s how the team built <strong>artificial neurons<\/strong> that are 1,000 times more energetically efficient than a living neuron, that is, they <strong>use about 1,000 times less energy to create the same electrical impulse<\/strong>. The reason is simple: an electronic neuron being 1000 times smaller than a living neuron, the ratio of sizes determines the ratio of energies.<br \/>\nAlain Cappy has opened up <strong>two avenues of research<\/strong> in the field of bioinspired architectures, which today constitute a research axis at IEMN and IRCICA. One, with Fran\u00e7ois Danneville and Christophe Loyez, aims to draw <strong>inspiration from the architecture of the brain<\/strong> to create intelligent and efficient vision systems. The other is a <strong>therapeutic approach<\/strong>, with Virginie Hoel, which involves the interaction of living neurons with artificial neurons to form implants for the treatment of neurodegenerative diseases. <strong>The Axorus start-up<\/strong>, created in 2019 and dedicated to the <strong>treatment of AMD<\/strong> (age-related macular degeneration), aims to enhance the value of 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":42661,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[297],"tags":[],"class_list":["post-42948","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-newsletter"],"_links":{"self":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/42948","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=42948"}],"version-history":[{"count":0,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/42948\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media\/42661"}],"wp:attachment":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media?parent=42948"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/categories?post=42948"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/tags?post=42948"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
