EEG<\/a>) and electrooculography (EOG). <\/p>\nBut unlike other bulky EEG caps, which monitor brain activity, this e-tattoo is wireless and paper thin and just has a small battery pack. <\/p>\n
In a study published in the Cell Press journal Device, the e-tattoo was tested on six participants who completed a memory test that increased in difficulty. <\/p>\n
As the participant\u2019s mental load rose they showed higher activity in theta and delta brainwaves, signalling increased cognitive demand, while alpha and beta activity decreased, indicating mental fatigue \u2013 showing the device can reveal when the brain is struggling. <\/p>\n
Currently the best way of measuring mental workload is the Nasa Task Load Index. This questionnaire is used by workers, such as astronauts after completing a task. <\/p>\n
But the e-tattoo can deliver continuous real-time data. <\/p>\n
It\u2019s also cheaper than current devices. Researchers say EEG equipment can exceed $15,000, while the e-tattoo\u2019s chips and battery pack costs $200, and disposable sensors are about $20 each. <\/p>\n
\u201cBeing low cost makes the device accessible,\u201d said author Luis Sentis from UT Austin. \u201cOne of my wishes is to turn the e-tattoo into a product we can wear at home.\u201d <\/p>\n
But currently the e-tattoo only works on hairless skin and researchers are working to make sensors that work on hair. This will allow for full head coverage and more comprehensive brain monitoring, study authors said. <\/p>\n
As robots and new technology increasingly enter workplaces and homes, the team hopes this technology will enhance understanding of human-machine interaction. <\/p>\n
\u201cWe\u2019ve long monitored workers\u2019 physical health, tracking injuries and muscle strain,\u201d said Sentis. <\/p>\n
\u201cNow we have the ability to monitor mental strain, which hasn\u2019t been tracked. This could fundamentally change how organisations ensure the overall well-being of their workforce.\u201d <\/p>\n","protected":false},"excerpt":{"rendered":"Your support helps us to tell the story From reproductive rights to climate change to Big Tech, The…\n","protected":false},"author":2,"featured_media":146857,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4317],"tags":[105,218,16,15],"class_list":{"0":"post-146856","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-mental-health","8":"tag-health","9":"tag-mental-health","10":"tag-uk","11":"tag-united-kingdom"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@uk\/114602607071924036","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/146856","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/comments?post=146856"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/146856\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media\/146857"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media?parent=146856"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/categories?post=146856"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/tags?post=146856"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
