Curved magnet edges
So I've read that coating failure is most common on the edges due to the coating not being distributed evenly on them, but you can't just eliminate the edges. Can you at least dial back the edges by making them more rounded instead of the 90° drop that we normally have, or would it not be beneficial?
I mean, like, a wider than typical magnet that's no thicker than a dime after coating. I imagine such a thing must be possible, structurally, basically my thought is that current magnets are still relatively thick considering they're often implanted in thin locations in the body, fingertips for instance.
It's one of the reasons that larger magnets become more difficult.
Not saying impossible, but food for thought depending on placement location. ^^
Blood circulation is important I suppose...
New idea... skin that doesn't need a continuous blood supply!
Any thoughts on that one? Mine all involve advanced robotics.
(That was a rhetorical question, no need to answer.)
I have a feeling that while there are some blood vessels that enter the skin for blood supply, but those entrances are entering a network of blood vessels that travel along the surface of the skin. So as long as the implant stays under such network and not cut through the entrance points, it should be fine.
Question would be how dense are those entrance points. Will be doing the skin module after a couple of weeks. Keep you posted.
And while every cell doesn't have direct contact to a blood source, doesn't that mean cells need to rely on one another or have those nutrients and oxygen somehow move among the cells? X_x
I think the roadblock comes in when you divide material, not that it's necessary cutting off veins directly, but simply interrupting transmission of needed resources.
I don't know enough about the body, other than this is my guess. Correct or validate me please. ^^'
In both scenarios the pathway does not run perpendicularly to the skin surface except for specific places. There has to be a reason why we don't tear apart capillaries to the skin every time we pinch our skin, say on the back of the palm, and that's what should happen if the skin just relies on capillaries that run vertically from muscles to skin (and also, every time the skin the stretched, so pretty much every time we move as well).
It appears that the whole skin (epidermis, dermis and the subcutaneous layer) as all supplied by what they call perforating branches. These are large vessels including both arteries and veins and comes out of the middle of muscles (and sometimes the edges of muscles i think). In fact, plastic surgeons have a technique where they cut out the skin, rotate it around the perforator, and sew it back on to close wounds etc. There is a very good article about it here, plus nice pictures of the perforator when the flaps are cut: https://www.researchgate.net/profile/Sandeep_Sebastin/publication/51048162_Clinical_Applications_of_Perforator-Based_Propeller_Flaps_in_Upper_Limb_Soft_Tissue_Reconstruction/links/5645455e08ae451880a8c43f/Clinical-Applications-of-Perforator-Based-Propeller-Flaps-in-Upper-Limb-Soft-Tissue-Reconstruction.pdf
These flaps can get really huge, which means that these perforators are pretty far apart depending on the location (would be much closer, say, for the skin on the back of my finger than the skin on my forearm), so basically, a flat implant placed underneath the subcutaneous theoretically should be able to get quite big before the perforators start getting in the way.
However, this is not going to be easy as we are now talking about placing implants on the deep fascia and pretty much right on the muscle (and builging muscles might cause problems). More problematic would be that we might need to cut out a whole section of skin to find the perforator in order to put an implant in - no easy task.
I wish I was more useful... lol ;_;
