You wonāt get endless glow out of body heat. If it charges with heat, it releases light energy when it cools down. Thermodynamics is a bitch: there aināt no free lunch.
Ah, thanks! Saw it some time ago, but I misunderstood it a bit - supposed it was UV-active stuff, not actual glow-in-the-dark-powder. At least here in germany, Iāve never seen anything glowy except for the standard greenish colour, so I might have worn blinkers on that 
Oh it would be so incredible to use that for implants or tattoosā¦ not a good idea, Iām afraid, but it would look amazingā¦

Thatāll be because itās over-coupled and consequently off frequency. Commercial tags are typically resonant high in frequency, usually around 14.8 MHz. The reason for this is the load pull of the reader. As the tag approaches the reader its frequency is pulled down and at some point youāll get optimal coupling, say 3cm or so. In this instance when you over-couple youāre still close enough in tune for it to work. Now taking that same commercial tag and slapping it on the back of your hand the resonant frequency wouldāve dropped to about 14.2 MHz. Iāve just tested on a 25mm NTAG. So now your optimum coupling could actually be about 5cm, and providing the tag is of reasonable size will work. But as you move it closer to the reader thereās a good chance youāll fall out the readers operating range (remember youāve detuned the tag by 600 kHz by placing it on the back of your hand) and things start to get flaky. Of course when implanted the frequency shift is probably greater. Big tags you can get away with things, but small tags are a different matter if you want optimum efficiency.

One of the first here. I have mine in the same-ish place that @anon3825968 has, and after the two or so months that Iāve had it, I can say itās practically invisible. I canāt really see it at all, except just barely when trying to force my wrist to bend into a shape that I would never do without trying specifically to see it.
I just noticed my arm is ever-so-slightly yellower than the other around the implant. Itās almost imperceptible, but I was sitting in a marketing meeting this morning at work, crossing my arms to subconsciously signal that I wasnāt really willing to participate in any of the bull that was flying across the table, and thatās when I noticed the subtle difference.
So I guess there is some blood under there after all.

There you are - charged it a bit with my UV-flashlight, simply because the room was not pitch black and I wanted to be able to take a picture without battling with my camera too much But thatās pretty much the look you get with bare eye when itās dark.
Second half is in broad daylight, and yes, itās still not āfinishedā - the skin in the middle will sink down a bit more, but this can take several months. Itās now almost 3 months old (one more week to go).

I have been thinking of putting the stars in that area, closer to the wrist.
Thank you for sharing!
Edit: Forgot to say this part first. That is awesome looking!

Thanks! Very groovy! The orientation is almost perfect too - that is, it hasnāt rotated flexNExT-style apparently.
Itās pretty bright. I like the lighting effect. The 3D lump under the skin howeverā¦ Uuh, not so much. I can tell rightaway if I had that under my wrist where you have it installed, it would quickly bother the hell outta me, seeing as though I spend most of my days with my wrists resting on a table typing away at the computer.
Aesthetically speaking, thereās something to be said for that device implanted at the back of the neck. It would be very Ghost in the Shell-themed I reckon.

Actually, I want the stars (3 of them, increasing in size - edit: decreasing! stupid meā¦) going from the implant āupā the arm, but, unfortunately, they are too flat for this area and wouldnāt be visible in normal light. But my artist and me are still working on a solution for that, Iāll keep you updated
Nah, no rotation at all - that thing is thick enough that the skin āgripsā to it and keeps it from moving. And the orientation actually is perfect, it just looks weird sometimes depending on how I hold my hand. If I just keep my arms relaxed down, it sits exactly in the middle 
Yep, that can actually get a bit annoying, depending on your desk setupā¦ when Iām on a gaming-marathon, I like to put something soft underneath it, then everythingās fine.
Iād absolutely love that, but those implants canāt be put above joints - and the spine is a massive collection of joints - and yes, I actually asked my artist on our first meet if he could do implants all the way up the spine^^ So Iāll be getting a ghost-in-the-shell / altered-carbon-style tattoo in my neck, some implants on my chest and arms, and the rest will be scars

Good news: touch feeling is starting to come back to the skin over the implant. The nerves are definitely reconnecting.
Aināt the human body wonderful? With all the stupid things we do to it, it still manages to sort itself out

Day 9: feeling is fully restored over 3/4th of the implant, with one sector still numb (opposite the scar line, strangely enough).
How long did it take for other flexNExT wearers?
With the flexNExT, not very long - Iād say maybe two weeks? On my silicone implant, it was much longer, about a month or maybe even two, and Iām honestly not sure if it is completely restored yet. I can feel touch and all, but it might be a little less than on other areas of my wrist. But itās surprisingly hard to tellā¦
Day 10: the stitches are out. I probably pulled them out too early, but the skin was getting very red and irritated all around the scar line, and the stitches were starting to embed themselves into the skin.
Fortunately, I put some strips across it 30 minutes after the removal, and that seems to have stopped the skin from tearing itself apart. Itās separated maybe 1 mm between the strips, and itās not really dry in the middle. But the redness seems to be going away slowly. Hopefully itās just irritation and not an infectionā¦
Uh ohā¦ Non-negligible fluid buildup over the implant now. Wtf?
I imagine that you irritated the area. Personally I would pressure wrap it to keep the fluid buildup down and take some Ibuprofen.
Way ahead of you there I had those things at the ready in my backpack.
I donāt think itās anything the piercer did (he removed the stitches). But maybe it has something to do with my resuming cycling yesterday. Maybe it was too early. Sports gets your blood pressure up real good.
Itās not a massive fluid buildup. The skin has lifted 3 mm maybe. So perhaps itās been there since yesterday. I only noticed now because the middle bit that had reconnected through the center hole of the doNExT suddenly went pop. When it did, I looked at my forearm and it was slightly convex instead of slightly concave. The touch feeling over the implant has vanished too.
Oh well. Itās wrapped up like a Christmas present. Weāll see what happens.

Had that very same problem - my body tends to hate the stitches before it decides to let the skin stick together -.- Got them taken out after about 14 days and wore strips for another full week, because the wound didnāt seem to be closed. After that, everything was fine.
And to the fluid buildup, that might really be because of the cycling. I still have a slight fluid buildup when I worked a lot with my hands, this goes away after less than a day, but it happens everytime I do too much, until now.
The swelling has gone right down - but Iām keeping the compression bandage on for now.
Yeah the cycling might have done it. Cuz ya know, it went without a hitch for 9 days, and now thisā¦ Iām a bit miffed actually. Thing is, 9 days without cycling is hard on me: I sleep less well and I feel restless when I donāt go out and spend some energy. Not to mention, winter is coming fast, and now is my chance to enjoy the last nice sunny days of the season.
So yeah, I probably should stay put, but I just canāt.
The wound is probably closed: whatever tiny seepage there is in the middle will scab over tonight. But youāre right: Iāll keep the strips for a while. Better safe than sorry.
Is the fluid buildup likely to continue or only during the healing process?
Iām pretty sure if it continues, itās not normal
I released the compression bandage to take a closer look at things, and I might have found the source of the redness - and possibly the fluid buildup:
When rotate my wrist, the doNExT slides ever so slightly right and left under my skin because it follows the radius and ulna more than the stretchy skin above does. When I supinate my hand as far as itāll go (palm up), the implant slides towards the radius and its edge bites the skin right at the edge of the drop around the bone. The skin is intact there, so no problem.
But when I pronate my hand all the way (palm down), the implant slides towards the ulna and its edge ends up biting the skin exactly under the wound. In fact, it slides just past it now
I think my installer made the pocket just large enough to slide the doNExT in and stitch the wound closed without poking the implant with the needle while my wrist was stationary on the armrest. But as soon as he was done and I started moving about, the implant started moving right and left and carving its own space, and the ulna-side edge started scraping against the underside of the wound and the stitches.
Iām thinking removing the stitches ended up releasing fluid into the pocket somehow - since the scar is now slightly over the pocket. Iām not big on anatomy, so maybe itās nonsense. But it seems like a reasonable explanation.
Anyhow, my wrist is now back to its original flat self. Iāll keep the bandage at low compression during the day and pop ibuprofene for a few more days to make sure it stays that way. As for the wound, it seems closed up and dry now. Still quite pink in hue, but nothing unhealthy-looking.
