400 nanometer of this metal stack and two micron of polyimide sandwiched together to protect it from the environment that is 37 degrees C bag of salt water.

Yeah, so the material selection that we have is not, I don't think it was particularly unique. There were other labs and there are other labs that are kind of looking at similar material stack. There's kind of a fundamental question and still needs to be answered around

the longevity and reliability of these microelectrodes that we call, compared to some of the other more conventional neural interfaces, devices that are intracranial, so penetrating the cortex, that are more rigid, like the Utah ray. that are these four by four millimeter kind of silicon shank that have exposed recording site at the end of it.

And, you know, that's been kind of the innovation from Richard Norman back in 1997. It's called the Utah Ray because, you know, he was at University of Utah.

Yeah. Yeah, so it's a bed of needle. There's... Okay, go ahead. I'm sorry. Those are rigid shank. Rigid, yeah, you weren't kidding. And the size and the number of shanks vary anywhere from 64 to 128. At the very tip of it is an exposed electrode that actually records neural signal.

The other thing that's interesting to note is that unlike Neuralink threads that have recording electrodes that are actually exposed Iridium Oxide recording sites along the depth, this is only at a single depth. So these Utah Array spokes can be anywhere between 0.5 millimeters to 1.5 millimeter. And they also have designs that are slanted so you can have it inserted at different depth.

But that's one of the other big differences. And then, I mean, the main key difference is the fact that there's no active electronics. These are just electrodes. And then there's a bundle of a wire that you're seeing. And then that actually then exits the craniectomy that then has this port that you can connect to for any external electronic devices.

They are working on or have the wireless telemetry device, but it still requires a through-the-skin cable. port that actually is one of the biggest failure modes for infection for the system.
