Mind-Reading e-Tattoo Monitors Stress, Privacy Concerns Rise
Researchers at the University of Texas at Austin have developed a noninvasive, ultra-thin e-tattoo that monitors brain activity in real time to predict mental fatigue, with potential applications in high-stakes professions. The device uses machine learning to analyze EEG signals and aims to provide timely interventions, though privacy and ethical considerations remain important. Its affordability and ease of use could democratize advanced brain monitoring technology.
