On the testing page you can see we tossed chips into liquid nitrogen… read fine after… I was amazed by that. Truly.
Yeah but… (putting my quality assurance guy hat here). It’s like fatigue failure vs stress resistance: low-level thermal cycling can be - and often is - more destructive than a huge thermal shock applied once. Because essentially, thermal cycling is fatigue failure: it’s repeated shrinking/expansion of the material. That’s what I’m testing here. Not the same test.
Mind you, this is all quite academic, considering no implanted chip will ever experience any of what I’m testing Still, like I said, if they survive those tests as well as yours, that’ll be proof enough that they’ll survive anything in-vivo.
I feel like this is on topic
I’m suddenly curious (and maybe a smidge concerned) about an x series getting hit but a simunition round (utm or sim) possibly even a paintball, but those have a much greater surface area to disperse their energy
Got a call into my force on force guy, to see if I can get some energy numbers
5.5mm diameter projectile
6.9grain / .45gram
310-375 FPS depending on delivery instrument
Most of the projectile’s energy will be dispersed into your meat.
Think of it as hitting your implant with a rubber mallet, or something that would leave a similar bruise on your skin: will it break a glassie? Possibly if you’re unlucky, but probably not.
I seem to recall Amal implanting a frozen chicken and hitting it with a hammer rather forcefully, but I can’t find it now. Do I recall wrong?
not sure there’s much meat between the implant and a projectile that small of it hits the mark
Crush testing up to 500N (maxing out the machine)
Here for the write up
I get that… but you’re talking about a broad force versus a very precise force
I’m talking about getting hit on an implant with a projectile the same size as the implant
You can hit a car window with a bat and usually not break it, but hit it with a punch and it fails,
Surface area of impact is far lower with my concern
It doesn’t matter because the implant isn’t backed against a hard surface: there’s squishy meat behind it also that tends to get out of the way.
But before it has a chance to “get out of the way” isn’t all force going to be transferred to the glass implant?
Amal, it seems to me it’s time for you to get the .50 out of the safe and hit the range. Testing is definitely needed here
It would be if the implant had enough mass and inertia to resist the acceleration. But an implant is very, very light - less than a gram. It won’t oppose anymore resistance than the meat behind it.
Thing is, if you apply enough force to break it, chances are you’ll have a significant injury yourself anyway.
I have various weapon lights and optics that have cracked lenses from these projectiles, and only small bruises
So I think it’s a valid thing to consider
It’s not un heard of for these projectiles to go into skin
Also, is that .50 mm or cm? If I didn’t know better I’d think you were speaking in inch’s lol
Of course it is. No question I was giving you my informed hunch. I’m sure in the right circumstances, bad things can happen to an implant.
12.7 mm BMG doesn’t roll off the tongue quite as nice
There’s no metric war here: a lot of ammo is denominated in inches, and listed as such in the European C.I.P. standards.
i mean… kinda… the crush tester is not an impactor it slowly and cruelly crushes while measuring exact forces. i could go for a thawed chicken haunch and just go to town on it with a meat mallet?
That does sound like fun!
Again, I think a hammer is a very different kind of impact force due to its limited surface are the force is applied
…I mean I’d watch
I just don’t know if it would be applicable
What about a ball-peen hammer? Could be very “to the point”… might try some different options
