The north of France has favourable weather for flax farming and fibre production. A process known as \u2018retting\u2019 is required to facilitate the mechanical factory extraction of flax fibres from their parent stems. During retting, the material between the fibres and the stem breaks down\u2014making mechanical extraction of fibres easier. There is an optimum retting period: insufficient retting time complicates fibre extraction, whereas prolonged retting leads to reduced fibre quality. <\/strong><\/p>\n<blockquote>\n<p><strong>Traditionally, the timing of the retting termination has been evaluated by agricultural artisanal means. In the context of Agriculture 4.0, modern technology enables one to envisage tools that predict optimal retting. A collaboration between IEMN, the UGSF, and the Van Robbaeys Fr\u00e8res company together with CNRS funds (80Prime project) enabled work in this area.<br \/>\n<\/strong><\/p>\n<\/blockquote>\n<p><strong>In the context of a PhD awarded to Ali Reda, we have conducted fundamental studies to understand the mechanical properties of flax stems and fibres on the macro-, micro-, and nano- scopic scales. Based on these fundamental studies, we have demonstrated the development of a smart tool (IoT) combining mechanics, digital microscopy, and image analysis. The cracking of the outer tissue of the flax stems, due to mechanical torsion applied by the tool, is quantified using optical microscopy and image analysis and serves as a novel indicator of the degree of retting of the stems. This enables the optimum retting stop-point to be identified. The study has led to the award of a PhD, six journal articles, a journal highlight, and a journal front cover.<\/strong><\/p>\n<p><strong><a href=\"https:\/\/www.mdpi.com\/2079-6439\/12\/10\/91\" target=\"_blank\" rel=\"noopener\"><span style=\"color: #ff7b00;\"><span style=\"color: #008080;\">\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-mqde7m-fcadd32f82eb0dd932cf0c9fadb5f2b8\">\n.av_font_icon.av-mqde7m-fcadd32f82eb0dd932cf0c9fadb5f2b8{\ncolor:#ff7b00;\nborder-color:#ff7b00;\n}\n.av_font_icon.av-mqde7m-fcadd32f82eb0dd932cf0c9fadb5f2b8 .av-icon-char{\nfont-size:25px;\nline-height:25px;\n}\n<\/style>\n<span  class='av_font_icon av-mqde7m-fcadd32f82eb0dd932cf0c9fadb5f2b8 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='\ue826' data-av_iconfont='entypo-fontello' ><\/span><\/span><\/span>Read the complete article here<\/span><\/a><\/strong><\/p>\n<\/div><\/section><\/div><div  class='flex_column av-kqgols-dc0a9e4c8955bd3bb72ecfe47a855c6e av_one_half  avia-builder-el-6  el_after_av_one_half  el_before_av_textblock  flex_column_div  column-top-margin'     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-m6gcgmw7-0bf766d624c2dad34beb45c4a4f3da83\">\n#top .av_textblock_section.av-m6gcgmw7-0bf766d624c2dad34beb45c4a4f3da83 .avia_textblock{\ntext-align:justify;\n}\n<\/style>\n<section  class='av_textblock_section av-m6gcgmw7-0bf766d624c2dad34beb45c4a4f3da83'   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p><strong><em>Output<\/em><\/strong><\/p>\n<hr \/>\n<ol>\n<li style=\"text-align: left;\">Dynamic micromechanical measurement of the flexural modulus of micrometre-sized diameter single natural fibres using a vibrating microcantilever technique.
