You know, electrochemistry, very robust, but we need to miniaturize it, right?

Because our microsensors are, you know, they're roughly the diameter of a human hair and a fraction of a millimeter in length.

So these are very, very tiny.

If you took the same chemistry from a traditional CGM and tried to just plop it onto our system, it would engulf our entire chip, right?

It's so small.

So we had to miniaturize it.

So we had to show that we could use the same techniques, but miniaturize it to fit our tiny array.

And...

In parallel, we had to develop this chip.

And what we found is that because these devices are so small, it had to be made out of something that's very mechanically robust.

If you took most materials and you said, hey, this is half a millimeter in length and it's the diameter of a human hair, it's either gonna bend or it's gonna break.

And that's really where silicon came in.

Silicon is stronger than titanium.

It's stronger than steel.

And so it's very, very robust and you can make it very sharp and you can use these techniques from the semiconductor industry to not only make these robust microchips, but you can also scale them.

So we knew that not only do we have to be able to make a prototype and run a first in human study, we have to be able to make, you know, millions, hundreds of millions, one day probably billions of these things.

And so that really was where all these worlds came together of

kind of standard approach for electrochemistry, novel approach for making the sensor itself, and then you combine those things together with our novel methods of chemistry deposition and you have the first intradermal sensor.

Yeah, for sure.

So there's a few steps required to get there.
