#438 – Elon Musk: Neuralink and the Future of Humanity

And at the end of the day, once you have the skin flap over, there's only about two to three millimeters that's obviously transitioning off of the top of the implant to where the screws are. And that's the minor bump that you have.

And the thread themselves also has a very interesting feature at the end of it called the loop. And that's the mechanism to which the robot is able to interface and manipulate this tiny hair-like structure. And they're tiny. So what's the width of a thread? Yeah, so the width of a thread starts from 16 micron and then tapers out to about 84 micron.

So, you know, average human hair is about 80 to 100 micron in width. This thing is amazing. This thing is amazing. Yes, most of the volume is occupied by the battery, rechargeable lithium-ion cell. And the charging is done through inductive charging, which is actually very commonly used. Most cell phones have that. The biggest difference is that for us,

Usually when you have a phone and you wanna charge it on a charging pad, you don't really care how hot it gets. Whereas for us, it matters. There's a very strict regulation and good reasons to not actually increase the surrounding tissue temperature by two degrees Celsius. So there's actually a lot of innovation that is packed into this.

to allow charging of this implant without causing that temperature threshold to reach. And even small things like you see this charging coil and what's called a ferrite shield, right? So without that ferrite shield, what you end up having when you have resonant inductive charging is that the battery itself is a metallic can.

And you form these eddy currents from external charger, and that causes heating. And that actually contributes to inefficiency in charging. So this ferrite shield, what it does is that it actually concentrates that field line away from the battery and then around the coil that's actually wrapped around it.
