Researchers use "e-tattoos" on scalps to monitor brain activity
Now, as reported by Live Science, researchers from the University of Texas at Austin have developed a way to use temporary tattoos for recording brain activity to...
They involve technicians using rulers and pencils to map out spots on your head, then gluing a bunch of electrodes across your scalp hooked up to a rat's nest of wires. Tests run on five people with short hair revealed that even with that thinness, the e-tattoos can pick up brain signals just as well as standard bulky electrodes. Since the conductive ink can be printed in thin hairline patterns, the team could use much shorter wiring to connect the e-tattoos to monitoring equipment.
