Scientists create liquid ink e-tattoo for brainwave monitoring, offering a wireless EEG alternative.

American scientists have developed a liquid ink e-tattoo that can measure brainwaves by being printed directly onto a patient's scalp. This hair-friendly technology, made from conductive polymers, offers a more comfortable alternative to traditional EEG tests. The e-tattoo electrodes performed comparably to conventional ones, with stable connectivity lasting at least 24 hours. The team plans to integrate wireless data transmitters to create a fully wireless EEG system, potentially revolutionizing non-invasive brain monitoring.
