A new hairlike electrode for long-term, high-quality EEG monitoring
- 6SixTy 2y agoThis 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.

- BriggyDwiggs42 1y agoDid they read and write brain signals with AI? What would the goal of that even be?
- postalrat 1y agoMany Black Mirror episodes explore this.
- BriggyDwiggs42 1y agoThe brain machine interface concept seems very useful. My question is the AI part. Aside from the machine learning likely needed to decode brain signals meaningfully at all, why would we want to hook up something with any resemblance to current AI to a brain directly?
- postalrat 1y agoThe current AI stuff can easily be described as a breakthrough in natural language interfaces. A field engineers have been working on for many years. It easy to imagine that the methods used to develop current AI could be used for different types of interfaces we've been stuck on.

- psunavy03 1y agoThat's not what an EEG is, and they have been around for decades.
- mmastrac 1y agoTerrible headline. The single hair-like electrode outperforms the connection performance (longevity/signal to noise) of a single electrode from a 21-lead EEG.
- hinkley 1y agoMy second mental image was an alligator clip connected to a hair on a person’s head.
- dn3500 1y agoIt'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.
- amelius 1y agoIsn'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.
