Dr. Nanshu Lu, the senior author of the research from the University of Texas at Austin<\/a>, wrote that mental workload is a critical factor in human-in-the-loop systems, directly influencing cognitive performance and decision-making.<\/p>\n Lu told Fox News Digital in an email that this device was motivated by high-demand, high-stake jobs such as pilots, air traffic controllers, doctors and\u00a0emergency dispatchers.\u00a0<\/p>\n TEEN GOES FROM 10 NIGHTLY SEIZURES TO ZERO WITH BRAIN IMPLANT<\/strong><\/a><\/p>\n Scientists say that they have formulated a way to help people track their brainwaves and brain usage. In a study posted in the journal Device, the team of researchers wrote that they found a more cost-effective and simpler way to track one\u2019s mental workload. (Dr. Nanshu Lu)<\/p>\n Lu also said ER doctors and robot\/drone operators can also leverage this technology for training and performance enhancements.\u00a0<\/p>\n One of the goals of this study was to find a way to measure cognitive fatigue<\/a> in high leverage and mentally straining careers.<\/p>\n The e-tattoo is temporarily attached to the subject’s forehead, and is smaller than current devices in use today.<\/p>\n According to the study, the device works by using electroencephalogram (EEG)<\/a> and electrooculogram (EOG) to measure both brain waves and eye movements.<\/p>\n 8 SLEEP TRACKERS TO HELP YOU GET A BETTER NIGHT’S REST<\/strong><\/a><\/p>\n While most EEG and EOG machines are bulky and expensive, this e-tattoo brings a compact and cost-effective solution to that problem. (iStock)<\/p>\n While most EEG and EOG machines are bulky and expensive, the e-tattoo offers a compact and cost-effective solution.<\/p>\n Lu wrote that in this study, “we propose a wireless forehead EEG and EOG sensor designed to be as thin and conformable to the skin as a temporary tattoo sticker, which is referred to as a forehead e-tattoo<\/a>.”<\/p>\n Lu<\/a> also added that “human mental workload is a crucial factor in the fields of human-machine interaction<\/a> and ergonomics due to its direct impact on human cognitive performance.<\/a>“<\/p>\n The way the study was conducted was with six participants being shown a screen on which 20 letters flashed up, one at a time, at various locations.\u00a0<\/p>\n The team found that as the tasks became harder, the different types of brainwaves detected showed shifts in activity that corresponded to a higher mental workload response. (iStock)<\/p>\n Participants were asked to click a mouse if either the letter itself, or its location, matched one shown a given number of letters.<\/p>\n Each participant carried out the task multiple times, corresponding to four levels of difficulty.<\/p>\n The team found that as the tasks became harder, the different types of brainwaves detected showed shifts in activity that corresponded to a higher mental workload response.<\/p>\n The device consists of<\/a> a battery pack and reusable chips with a disposable sensor.<\/p>\n![\"Scientists](\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/05\/blurred-eyes.jpg\")
