The neat bit:
"The second closest magnetic bead pair, with an initial separation distance measured
at 16.7 mm, did not fully migrate, and was measured at a final separation distance of 13.8
mm at conclusion of the study. In contrast, beads at longer separation distances, above 21.5
mm, were resilient to migration at long timescales (n = 13), suggesting that these magnetic
beads can be safely implanted with separation distances above 21.5 mm. Notably, the bead
pairs at these longer separation distances actually increased in separation distance over the
six-month study (increase of 4% +/− 3%), possibly due to the growth of the turkeys over
this time period, though small changes in distance for any particular pair of beads could have
resulted from changes in passive muscle properties or small variations in positioning the bird
for different measurements.
"
Basically, there is actually a Goldilocks zone where the force of the magnets counteract the natural migration of the magnets in the tissue.
Just found the whole paper fascinating and thought I’d share.
I would love any recommendations for works they have contributed to. I read a lot of papers like this when I’m procrastinating my homework, which I’m doing quite hard right now.
I can’t say I can name any, tbh. I am familiar with him by his, ah, circuitous path to MIT. Here is an interview, if you’re looking for something to listen to while you’re studying
@Az_F do you think any of the Lodestone magents would be viable for testing something like this? I may not be willing to do a fingertip install at this point, but… My forearms are free use right now.
Yes but it looks like the magnets need to be in the muscle. You might be able to perform this with a needle and the tiny 3824 but that’s new territory.
The skin does follow the muscle movement but I assume you’d loose in accuracy and couldn’t target one specific muscle as well?
Besides, I’d make someone else do it, so I’m not really stabbing myself here
I see. I will prod at my installer to see how viable this could be… I bet money they won’t do it, but I also know they’ll be honest whether its plausible.
The fact that it’s bigger. And also I think it would be best for it to be aligned with the muscle fibers so that it interferes as little as possible. In the arm that would be hard to do sonce you will likely enter perpendicular to the muscle fibers.
I’m not exacly knowledgeable about muscle implants so I’m just speculating. I think both would work but if I were to do it I would want the implant to be as small as possible
Yea, the shape of the magnet makes a big difference in viability when talking about intramuscular implants.
In muscle, as close to a sphere as possible is ideal. With an oblong implant, the tensing and relaxing in the muscle tissue surrounding the implant would, at the least, cause a sensation, and it would probably be uncomfortable.
A sphere prevents this by making the pressure exerted during movement as uniform as possible.
Finally, sub dermal wouldn’t be optimal for this technique as the density and elasticity of the tissue is different and not as predictably mobile like muscle tissue is.
Would it be worth looking into recreating (buying a custom batch) of similar magnets to what they’re using here? 3mm n52 spheres, gold basecoat, maybe some other harder layer on top?
Hey I could probably use a 3mm glassie injector for that.
Not specifically spheres but any small implantable magnet. Spheres would be even harder to find because they are harder to manufacture and more rare.
A layered coating is worth it if the properties of each layer combine to make it better. Like a very hard material on top of a very impermeable one so the coating is both resistant to wear and fluid ingress.
Gold as a last resort is not useful because if everything above fails then the gold doesn’t stand a chance either
I guess I’m a doctor now
