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