This is actually an improvement on the lead electrode technology, making them smaller and improving the scalp adhesion for better fidelity. Ostensibly, you would still need an array of them for medical diagnoses, like isolating and/or monitoring a seizure to a particular portion of the brain.

Terrible headline. The single hair-like electrode outperforms the connection performance (longevity/signal to noise) of a single electrode from a 21-lead EEG.

My second mental image was an alligator clip connected to a hair on a person’s head.

It's not just the headline. "... a single electrode that looks just like a strand of hair and is more reliable than the standard, multi-electrode version." "The researchers tested the device’s long-term adhesion and electrical performance and compared it to the current, standard EEG using multiple electrodes."

I read the story three times and I'm still confused. But I'm sure you're right, and I think it's the author who's confused.

Isn't that circular pad the electrode, and the "hair" just the lead which can be replaced by any copper wire?

Better link from Penn State. My reading of this seems to suggest that these electrodes are better than the standard one, NOT that one electrode is better than 24 leads.
