some magnet implant related questions
I'm intending on installing a set of magnets in the relatively near future and am assembling materials. There are, however, a few questions I have remaining before I sugru the magnets and install them.
first is relating to magnet size, position vs sensation. my intent is to use long thin cylinders, about 1.5mm x 5mm with poles at each end. I intend to place them in my ring fingers on the side opposite my thumb on each respective hand. my intent was to keep them in a nerve rich area, while keeping them out of areas that get touched and messed with a lot. I have noticed that disk magnets appear to be the standard - does the size and shape of the magnet significantly affect the sensation that the final implant will deliver? if there is not an appreciable reduction in sensation due to the use of smaller magnets, I may even try out magnets as small as 1.6mm x 0.8mm (disks). similar question regarding positioning on one's fingers - will my choice of implantation site have any major effect on the sense?
my final inquiry revolves around the recent interest in the use of medical grade implants rather than DIY ones using sugru. my understanding is that some implants using sugru failed and began to degrade. did this occur due to the sugru breaking down somehow, or was this an issue of an incomplete or damage coating?
