Imagine sticking on a digital 'tattoo' that tracks your mental stress in real time. Researchers are testing ultra-thin, skin-like wearables that read brainwaves and eye movement—no more clunky headgear or sticky gels. Sure, it’s a breakthrough for high-stress jobs, but would you trust a forehead sensor to monitor your focus or relaxation? Is this the next step in wearable tech, or does it cross a line? Let’s debate: where should we draw the line between innovation and privacy? #WearableTech #BrainwaveMonitoring #DigitalTattoo #Tech
