Implant in foot: practical problem

That sounds unsafe. If I miss the subdermal layer, I’ll punch right through the transverse ligament underneath. There ain’t no muscle there.

I could. The skin looks a bit less taut further back. But then I won’t be able to drop the chip where I want - which is all the way forward. I want it there so it’s as close to the ground as possible, but also so it’s well protected in the deep recess between the phalangeal bones. Also, I don’t want it to end up between the metatarsal heads for the same safety reason.

Well, I was about to go bevel up anyway - I always do bevel up :slight_smile: But I don’t feel confident punching through the skin at an angle, and neither does my piercer. Like I said, at that location, there’s no cushioning under the skin: if I mess up, I damage the ligament.

Maybe I’ll try one of the micro-clamps they use at the office to hold onto miniature eletronics: if I tighten it hard enough, it’ll pinch the skin and then I can lift it up, and the clamp won’t get in the way under the tent the way my fingers do. Maybe pop a couple ibuprofen pills half an hour before doing it: pinching the skin there is surprisingly painful.

I agree, but if I really wanted it there, I would try if I had to.

your needle would likely catch, i have hit a few tendons in my time. With 23 or 21 gage needles.

Arch of your foot on the bottom? Pretty soft there.

Also hemostats with a couple of rubber bands around it might work.

Ah, never tried it. I will have to.

No way I’ll implant anything there. I’m a barefooter, I like hiking, and I can’t count the number of times I’ve stepped on really rough stones and pebbles that don’t penetrate the skin, but deform it enough that anything underneath could certainly break. Even under the fat pads would be a significant risk I think - not to mention, good luck getting a needle to penetrate the hardened soles and thickened fat pads of someone who’s been walking barefoot for 20 years :slight_smile:

I’ve decided to inject it on top of the foot, but at the lowest point to the ground, which is the webbing between the big toe and the second toe. That places it roughly 20mm above ground, which is plenty close enough for my long-range readers. And if I read it from above (reader under the rear bumper of my van) it won’t even have to be long range. Also, it’ll sit under both bones there, so it’ll be protected even if I hit something with the top of my foot, and it won’t become uncomfortable for the odd times when I do have to wear shoes.

It’s in:

Tenting up the skin was a real bitch. But my piercer had a technique I didn’t know, which is to roll up and massage the skin into loosening. That made things a bit easier, but not much. Pinching and pulling hard enough on it to create an entry point was way more painful than the implant job itself.

It’s quite a bleeder though: the piercer waited 15 minutes for hemostatis, but could never achieve it. In the end, he put a bandaid on it, and some special tattoo cling film to contain the mess. One hour on and it’s bleeding - or maybe it’s stopped already, I can’t really tell under the cling film:

I wonder if an RFID chip in the foot :syringe: :foot: is a first :interrobang:

If not, I’m sure putting a slice of salami on a wound as a band-aid :adhesive_bandage: has got to be a first !!!

@anon3825968, you are welcome for the emojis :stuck_out_tongue_winking_eye:


It ain’t no salami, it’s a small bandaid with an almost invisible clear film sticker around it, and blood trying to gush out underneath :slight_smile:

As for the emojis, well it’s like my neighbor’s toddler who keeps on crying and screaming for hours: as much as I want to bang her head on the wall until she finally shuts the fuck up, I can’t. So I just bite my lip and let it run its course…

Sure thing @anon3825968 , You’re not fooling anybody :no_entry_sign:

When is the maiden voyage of implant meets reader?
What chip have you actually put in?

@leumas95, another one for your implant sutra


It’s just a xEM. It’s actually met my LF keyfob reader already, which I brought along with my cellphone and an OTG cable to check that it reads correctly - or more accurately, that it stayed behind in my foot after the needle was pulled out. I’ve had chips coming back out with the needle, even with the plunger fully depressed, sticking to the end of the needle by capillarity with the blood.

It reads from the top with the keyfob reader alright, but not from the bottom. That was to be expected. This evening I’ll see if it rings with my long-range reader from the bottom.

Put the antenna under one of those desk foot rest things and every time you sit down it unlocks

also, what is that antenna/reader?

That’s the plan. That and a reader as a door mat to unlock my front door. And a reader under the bumper of my car, to unlock it when I’m carrying the groceries, and (if it works, I haven’t tried yet) an xAC antenna under the gas pedal to start it up. Look Ma, no hands!


Very cool concept come to life. :foot: :signal_strength:
Nice work @anon3825968

I made a little inclined stand for one of my long-range readers in the company’s workshop this morning, so I can present my foot comfortably to the reader when it’s under my desk at work:

And now I can do magic tricks at the office:

@leumas95 time to update implant sutra?

I gotta say, as unusual as it is, I love this idea :smile:
