Researchers from The University of Texas at Austin have introduced a novel e-tattoo designed for facial application that can detect mental stress and cognitive strain by decoding brainwaves. Unlike traditional EEG caps, which are cumbersome and use wires, this innovative tattoo utilizes thin, flexible sensors that conform to the user’s skin, primarily on the forehead. It captures brain signals and eye movements to monitor mental fatigue effectively. The study's findings reveal that this device can accurately predict when an individual is experiencing increased mental stress or fatigue during cognitive tasks, marking a leap forward in wearable health technology.
The e-tattoo wirelessly decodes brainwaves and detects mental stress by using thin, skinlike sensors that adhere to the forehead, outperforming traditional EEG caps.
Researchers demonstrate that as tasks become challenging, brainwaves indicate increased strain, with alpha and beta waves dropping to reflect mental fatigue.
