Come on down to crazy Amal's flex-o-ramma-ramma!

Much better explained but exactly what I was picturing in my head.

That’s a shame. Maybe not blocking the led would work. Like coat the outside but don’t block the led. I assume there’s enough diffusion in the flesh that the light would charge it and be visible?

Either way, I want that bar of LEDs :sweat_smile: maybe even more? 5x2 prehapse :thinking: I love the BLINKY :heart:


how many segments do you want? i assume glow resin as well… I have 10 of these light blue LEDs… I can quote you out a custom job… but I’ve run out of time for playing around today.

The total width would be 14mm and length would depend on the segment count… each are 9mm… but overlapped they are 15mm for 2 segments… but with double overlapping I can get 3 into 18mm… 4 into 25mm… plus add 2mm for safety margin… just to give you an idea of the possible size we’re talking about.


How wide do you think would be safe across the width of the wrist?
I reckon 5 would fit (32mm + margin) and be great. Do you think adding a normal flexNT to it would cause issues? Seems like the right size and would make the implant at least a tiny bit practical.

Resin would be great if it’s not going to make the whole thing super dim. I’d rather spectacular effects when lit up than mediocre all around. So yeah maybe “a drop of resin”

Either way, I’m very interested, I’ll DM you tonight and you can get to it when you have time (not exactly in a rush ATM with the lack of access to piercers)

That ended up a lot stiffer than I expected. You were right, no backing needed.

Yep, that’s a much better idea. Maybe have the FlexEM overlap a “dead” part of the antenna, or the HF tag’s chip itself (which I assume is the large area above the “+”) so that it’s stiffer and less prone to failing if the HF tag flexes under the skin?

I definitely would implant something that lets the skin reattach in the middle.

Damn. My clever attempt at fooling people is foiled :slight_smile:

Off topic, so I am hiding my reply to @Rosco

I thought you did a good job of matching the art style of his head to the body, I initially thought It was an avatar you rendered in a videogame that I wasn’t familiar with, especially after seeing @Aemun follow up post


Well thanks. But actually it’s all kinds of wrong: the light comes from the wrong direction, the color is wrong, the shades are wrong, the grain is wrong, the neck mucles don’t blend in. But hey, it’s a 5 minute job.

And yeah, off-topic :slight_smile:

yeah I think 5 makes the most sense if you want it across your wrist. What is the thickness of your wrist at that point out of curiosity?

No not at all… the resin settles out so the area above the LED can be made super thin… but it does add a lot of rigidity which I don’t like. I can look into using low durometer silicone to ensure it remains flexible, but I don’t have any at the lab so I’d have to order it in… would extend the ETA a bit.

As you’ve identified, that little black dot is the chip. It’s flip chipped to the substrate and fragile. I wouldn’t want to put something directly over it, but exactly next to it, that might make good sense.

Hard to say… since it is rounded. About 38mm of space without curve. On the hand side of the tape measure.

As I said, not in a rush with COVID, flexibility sounds better.

This thread has me like


Weird theoretical question - could the same coil be used for LF and HF to optimise space?

As in, a coil wound for 125kHz with a ‘centre tap’ (since it’s basically a transformer winding) at the point for 13.56MHz?

Manufacturing could be difficult, but would allow a very small dual-frequency flex if you could pull it off

Yes. Just like a dual tapped inductor, it’s possible. Difficult, but possible. In fact, the Toorcamp version of the RFID diagnostic card does this…

It’s already hard enough to get a single wound screens sized and tuned properly… I can’t imagine doing this.


This raises an interesting possibility, for those looking to extend the range of existing implants, or improve performances for glass implants that DT doesn’t offer a big-ass version of: a sort of “booster” implant that can be threaded under the skin. Added advantage: if the booster implant fails or gets damaged, the transponder remains functional - possibly even with a minimal decrease in performance, if the damaged booster still shapes the magnetic domain enough to have a beneficial effect.

Of course, for that to happen, it would have to be an open length of wire (or polymer-coated wire I guess). Otherwise, if it has to be a loop it’s back to butchery. Do you know if a partial circle also guides the magnetic flux?

Also, somewhat related, I wonder if a similarly-shaped tattoo around a glass implant with a ferrite-based pigment might yield similar results. Hmm… I’m almost wanting to grind some ferrite in mineral oil and paint my hand to give it a spin…

Do it! For science!

Yeah well, for science to happen, I’d have to get off the couch and leave my brewsky there, and that ain’t happening :slight_smile:




I subscribe to Adam Savage’s philosophy that the only difference between screwing around and science is writing shit down. The beer can come with you! Science can happen on the couch!


Can i suggest we refer to these as something like ‘FlexPlus’ - just to avoid muddying the water on what a Flex implant is - these seem like a very different beast!


SuperFlex is my vote or Flexenstine
