Scientists at the University of Texas at Austin have developed a groundbreaking technology that uses temporary electronic tattoos to record brain activity. This innovation provides a faster and more convenient way to monitor brain functions for neurological conditions like epilepsy and brain tumors compared to traditional electroencephalograms (EEG). During trials, the tattoos demonstrated similar effectiveness to conventional electrodes while maintaining signals for longer durations. The researchers believe this technology could revolutionize non-invasive brain-computer interface devices, pending further validation.
