In particular, these measurements enable us to develop MAC layers that are adapted to the highly changeable environment that objects can encounter.<\/p>\n<p><a href=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2018\/04\/groupe_csam_objets_connectes_cloud.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-16879\" src=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2018\/04\/groupe_csam_objets_connectes_cloud.jpg\" alt=\"\" width=\"526\" height=\"238\" srcset=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2018\/04\/groupe_csam_objets_connectes_cloud.jpg 1200w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2018\/04\/groupe_csam_objets_connectes_cloud-300x136.jpg 300w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2018\/04\/groupe_csam_objets_connectes_cloud-768x348.jpg 768w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2018\/04\/groupe_csam_objets_connectes_cloud-1030x466.jpg 1030w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2018\/04\/groupe_csam_objets_connectes_cloud-705x319.jpg 705w\" sizes=\"auto, (max-width: 526px) 100vw, 526px\" \/><\/a><\/p>\n<\/div><\/div><\/div><\/section>\n<\/div>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-lxeqmwim-7616655a57a77d08b3a47bf568d1b39a\">\n#top .av_textblock_section.av-lxeqmwim-7616655a57a77d08b3a47bf568d1b39a .avia_textblock{\ntext-align:justify;\n}\n<\/style>\n<section  class='av_textblock_section av-lxeqmwim-7616655a57a77d08b3a47bf568d1b39a'   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock'  itemprop=\"text\" ><blockquote>\n<p>Neuromorphic technologies offer processing capabilities combined with improved energy efficiency, which is crucial for the IoT .<\/p>\n<\/blockquote>\n<p><a href=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/06\/CSAM_Neuro.webp\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-65702 alignleft\" src=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/06\/CSAM_Neuro-300x300.webp\" alt=\"\" width=\"230\" height=\"230\" srcset=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/06\/CSAM_Neuro-300x300.webp 300w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/06\/CSAM_Neuro-80x80.webp 80w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/06\/CSAM_Neuro-12x12.webp 12w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/06\/CSAM_Neuro-36x36.webp 36w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/06\/CSAM_Neuro-180x180.webp 180w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/06\/CSAM_Neuro.webp 400w\" sizes=\"auto, (max-width: 230px) 100vw, 230px\" \/><\/a>This area is based on a bioinspired approach to information processing and transmission system architectures.

This technology is currently the subject of a cluster of 7 patents and can be adapted to different modalities (vision, acoustic waves, electromagnetic waves) by means of neural spike encoders capable of addressing physical quantities (luminance, sound intensity, electromagnetic power) but also metrics (e.g. difference in arrival time) with energy consumption down to a few picoWatts.<\/p>\n<p style=\"text-align: left;\"><span style=\"color: #808080;\">_________________________________________<\/span><\/p>\n<p><span style=\"color: #f16728;\"><strong>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-mqde7m-1-ec2c04f41b7420486817f2e799a043b8\">\n.av_font_icon.av-mqde7m-1-ec2c04f41b7420486817f2e799a043b8{\ncolor:#f16728;\nborder-color:#f16728;\n}\n.av_font_icon.av-mqde7m-1-ec2c04f41b7420486817f2e799a043b8 .av-icon-char{\nfont-size:25px;\nline-height:25px;\n}\n<\/style>\n<span  class='av_font_icon av-mqde7m-1-ec2c04f41b7420486817f2e799a043b8 avia_animate_when_visible av-icon-style- avia-icon-pos-left avia-icon-animate'><span class='av-icon-char' aria-hidden='true' data-av_icon='\ue805' data-av_iconfont='entypo-fontello' ><\/span><\/span><\/strong><\/span>Contact : Christophe.loyez <img loading=\"lazy\" decoding=\"async\" class=\"align=absbottom wp-image-73424\" src=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2035\/05\/arobase_noir.png\" alt=\"\" width=\"14\" height=\"14\" srcset=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2035\/05\/arobase_noir.png 24w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2035\/05\/arobase_noir-12x12.png 12w\" sizes=\"auto, (max-width: 14px) 100vw, 14px\" \/> imt-nord-europe.fr<\/p>\n<\/div><\/section>\n<div  class='togglecontainer av-lxercqua-7ea91266ff4c33d3ff73cf9b0ccad1f1  avia-builder-el-9  el_after_av_textblock  avia-builder-el-last  toggle_close_all' >\n<section class='av_toggle_section av-lxerco9h-316e0ea473dc646e6c53c304f6bacfaf'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div role=\"tablist\" class=\"single_toggle\" data-tags=\"{All} \"  ><p id='toggle-toggle-id-4' data-fake-id='#toggle-id-4' class='toggler  av-title-above'  itemprop=\"headline\"  role='tab' tabindex='0' aria-controls='toggle-id-4' data-slide-speed=\"200\" data-title=\"Wake-up receiver\" data-title-open=\"\" data-aria_collapsed=\"Click to expand: Wake-up receiver\" data-aria_expanded=\"Click to collapse: Wake-up receiver\">Wake-up receiver<span class=\"toggle_icon\"><span class=\"vert_icon\"><\/span><span class=\"hor_icon\"><\/span><\/span><\/p><div id='toggle-id-4' aria-labelledby='toggle-toggle-id-4' role='region' class='toggle_wrap  av-title-above'  ><div class='toggle_content invers-color'  itemprop=\"text\" ><div id=\"attachment_65703\" style=\"width: 167px\" class=\"wp-caption alignright\"><a href=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/06\/CSAM_wakeup.png\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-65703\" class=\"wp-image-65703\" src=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/06\/CSAM_wakeup.png\" alt=\"\" width=\"157\" height=\"126\" srcset=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/06\/CSAM_wakeup.png 237w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2024\/06\/CSAM_wakeup-15x12.png 15w\" sizes=\"auto, (max-width: 157px) 100vw, 157px\" \/><\/a><p id=\"caption-attachment-65703\" class=\"wp-caption-text\">Bioinspired receptor using CMOS technology<\/p><\/div>\n<p>The CSAM group is developing a new generation of bioinspired receivers capable of constantly monitoring the radio channel to identify a specific electromagnetic signature, with energy consumption of just a few dozen nanoWatts.
