What is the size of the needle in an artificial pancreas or continuous glucose monitors?

Thanks, can I ask please, does the microneedle suck body fluid up to the device and the glucose is measured there or the tip of the microneedle senses glucose under the skin?

Thanks!

I found this through Google, maybe it's helpful.

It’s basically an electrode. The enzyme within the filament reacts with glucose in the fluid between the cells and created an electrical signal. The body of the sensor collects this and the data is transmitted to the scanner or phone where a lot of complicated coding and algorithms interpret it and give you your bg reading.

You can’t make one at home.
