Interesting. Did you try with the sticker tag cut across the coil - firstly to disable the tag so whatever it “boosts” can reply to the ACS122 instead of the sticker, and also to test whether an interrupted coil acts as a booster also?
I’m pretty sure there’s a viable product to be developed here…
What the actual fricking physics.
Is there a way these antennas can be printed on a recycled degradable plastic (maybe with holes for air) with biosafe glue?
I’d pay 5 bucks each depending how good it is for my skin to keep them on for a long time. Perfect for hotel stays etc.
What If we place one of those under an eGeeTouch with like 5mm spacer, would that enable it to read the x implants?
That most definitely would not work. You need the inductor loop of the large tag to be complete in order for the boosting to happen. Otherwise the large tag is just a spaghetti pile of copper in the way of the field. Check out this video to see the difference between a cut and uncut inductor.
You could remove the chip and replace it with an equivalent capacitor.
It does make sense that this would happen. There’s just never been a reason for us to mate these two antennas shapes before this. Here’s an image of the field shape being created as the large tag interacts with the reader
See how it pulls the field through the center and then around the wires on the top so that they’re now traveling horizontally instead of vertically? If you rest an x-series implant there then the field lines would be traveling right through the center of its small coil.
Remember Amal’s wise words that magnetic fields are kind of like soap bubbles. It’s kind of like the large tag is better at pulling on the bubble created by the reader, because it’s large and doesn’t break the surface tension. Then as the large tag pulls the bubble larger, it’s easier for the x-series tag to rest on the surface and piggyback off of the larger one.
I know. The coil acts as a kind of transformer’s primary. It’s just… sometimes, stuff works. Like I said, if the boosting occured with an incomplete loop for some odd reason, then it’d open the possibility of making an easily implantable booster device that doesn’t require extensive skin slicing to install.
Years agon, (agon was a mistype, but I like it, so i’m keeping it) I had a book, really more of a a pamphlet, that showed how to make an electromagnet for picking up aluminum. This was just at the begining of my being electro-curious, so I didn’t retain specifics.
The idea is that a magnetic field would induce an electric current in the aluminum, which would creat it’s own magnetic field that would oppose the original field. This is how rail guns work.
The trick was using alternating copper/steel layers in the electromagnetic core to somehow twist the field back against itself causing it to attract instead. Kind of a “suck it in” rail gun effect.
With this in mind, and understanding this is likely to be a mental nightmare to design, could a dummy coil be designed to concentrate the lines of flux to a specific location? If you could squeeze the magnetic field to a specific point, and aim it at an implant, then exceptional range, correct?
