Why not ? It would be fun and I say yes if there is no risk to health.
I think having a glowing implant would be awesome if it was not radioactive material.
- If I had to use my phone to trigger the glow, I’d pass on getting one.
- I wouldn’t mind the increase in size to accommodate a battery. I’d definitely go get that professionally done. Jeesh, sounds big!
- Sure, a belt that powered the glow sounds super discrete too.
1, I have already one - there is also a discussion about this implant in this forum
I bought it from an otehr store - my implant is fine. (got it in February 2019)
no battery for me. How would you turn on and off the LED?
no - for me would this a problem, we are not allowed to wear, rings, braclets and smimilar stuff at work
I think a cool approach would be building a implant like the XLED but adding a capacitor inside that would charge when brought close to a phone or reader and keep the LED lit or a heartbeat flash for 30 seconds or so after removing the power source.
Yeah, I like that idea too!
Here is the highest Farad capacitor (200mF) I could find with a Z-height that was remotely possible for implantation (1.4mm). If the LED is running at ~3V, the math for how long it would last would look like this:
Farad = Coulombs/Volt
(200mF) = Coulombs/(3V)
Coulombs = 0.6
Amp-hours = Coulombs/Seconds in an Hour
Amp-hours = (0.6)/(3600)
Amp-hours = ~167μAh
If a tiny LED required 15mA to reach full brightness, that means it would last:
167μAh/15mA = 0.011h = ~40 seconds
That’s a pretty big implant for 40 seconds of illumination. Some other biohackers I know are working on developing their own high density Supercapacitor to address this problem, but it’s not exactly viable as an off-the-shelf solution at the moment. We’re pretty much stuck with chemical batteries or magnetic field power.
Tritium would not work even if it was non radioactive (personally I do not think the radiation is an issue, it is the lack of light radiation that is a problem.
In a pitch black closet you can barely see it thru the skin when folded like in the picture and it is even worse between the thumb webbing, so unless you want to take your friends into a dark room to show it off, it would just be a useless little bump. This is a pretty beefy and fresh vial too.
It is almost known for being underwhelming even on the surface of wristwatches
Quite interested in LED though.
I don’t see a need for it, but it seems interesting enough.
What would be the charge time for that capacitor?
I’d have to test to verify, but here’s the calculation with gud enuf values:
R * C = τ
(1Ω) * (200mF) = 0.2 seconds
Charge time ≈ 5τ
Charge time ≈ 1 second
What if you got that wire (just coated copper) to create an induction coil to nowhere and put it inside some glass.
That’s really cool. I was initially skeptical, but it looks like that guy really did put some EL wire in his arm.
Did you mean putting a tiny piece of electroluminescent wire in the implant glass?
like the induction coil people are recommending for charging (like qi wireless charging) but make it with the electroluminescent wire so the coil itself glows.

Wow. You just blew my mind. Let me think about that for a bit. In the meantime, here’s the layout of the EL wire:
It’s basically a coiled capacitor being charged up to ~120VAC @1kHz
That looks really interesting. But also looks like it would be huge.
With the sleeve they can be 2mm in diameter.
Awesome. I bought one earlier today. Can’t wait to get it!
Just out of curiosity, any thoughts of combining the xNT with the 13.56Mhz xLED or an xEM with a 125kHz xLED, sort of like the NExT, but with more pizzaz and less functionality?
I would definitely buy that if they released that. It would also show if the chip was within the correct distance within the reader.
