Researchers at the Institute of Semiconductor Physics of the Siberian Branch of the Russian Academy of Sciences<\/a> have developed a wearable stress monitoring<\/a> sensor that attaches to the arm and measures stress levels through the skin.<\/p>\n\n\n\n The device detects cortisol concentrations and other stress indicators found in sweat. As a result, it enables more direct tracking of psychological and emotional states.<\/p>\n\n\n\n Monitoring stress is important for early detection of serious conditions. It also supports lifestyle adjustments and helps maintain mental health.<\/p>\n\n\n\n However, the researchers noted that existing solutions often lack sufficient sensitivity to cortisol. In addition, they cannot accurately track real-time changes in emotional states. Many systems are also costly and rely on indirect indicators, such as skin conductivity or antibody-based methods. Consequently, their effectiveness is limited.<\/p>\n\n\n\n The new device aims to overcome these challenges. It is low-cost, easy to manufacture and simple to use. At the same time, it delivers more precise results.<\/p>\n\n\n\n The sensor achieves high sensitivity to cortisol using a flexible substrate. This substrate is coated with an ultra-thin, 20-nanometre layer of a conductive composite material. The material includes graphene, an organic polymer and ethylene glycol. Together, they reduce electrical resistance and enhance sensitivity. Moreover, the layer can be applied using two-dimensional printing or drop-casting techniques.<\/p>\n\n\n\n The researchers explained that sweat contains about 98 percent water and 2 percent chemical compounds. These include salts, oxygen, glucose, adrenaline, cortisol, dopamine and enzymes.<\/p>\n\n\n\n The sensing unit is worn on the wrist. This allows sweat to interact with the sensitive layer. As a result, charge accumulates and the electrical conductivity of the sensor increases, supporting accurate stress monitoring.<\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" Researchers at the Institute of Semiconductor Physics of the Siberian […]<\/p>\n","protected":false},"author":58,"featured_media":105044,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[54,9624],"tags":[9261],"contributor":[9732],"class_list":["post-105039","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-health-tech","category-smart-sectors","tag-healthtech","contributor-news-desk"],"featured_image_src":"https:\/\/techxmedia.com\/en\/wp-content\/uploads\/2026\/04\/Russian_English-copy-11.jpg.jpeg","author_info":{"display_name":"Lubna","author_link":"https:\/\/techxmedia.com\/en\/author\/lubna\/"},"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/techxmedia.com\/en\/wp-json\/wp\/v2\/posts\/105039","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/techxmedia.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/techxmedia.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/techxmedia.com\/en\/wp-json\/wp\/v2\/users\/58"}],"replies":[{"embeddable":true,"href":"https:\/\/techxmedia.com\/en\/wp-json\/wp\/v2\/comments?post=105039"}],"version-history":[{"count":1,"href":"https:\/\/techxmedia.com\/en\/wp-json\/wp\/v2\/posts\/105039\/revisions"}],"predecessor-version":[{"id":105040,"href":"https:\/\/techxmedia.com\/en\/wp-json\/wp\/v2\/posts\/105039\/revisions\/105040"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/techxmedia.com\/en\/wp-json\/wp\/v2\/media\/105044"}],"wp:attachment":[{"href":"https:\/\/techxmedia.com\/en\/wp-json\/wp\/v2\/media?parent=105039"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/techxmedia.com\/en\/wp-json\/wp\/v2\/categories?post=105039"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/techxmedia.com\/en\/wp-json\/wp\/v2\/tags?post=105039"},{"taxonomy":"contributor","embeddable":true,"href":"https:\/\/techxmedia.com\/en\/wp-json\/wp\/v2\/contributor?post=105039"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
