I often find myself maneuvering my finger close to objects to take in any sensations that may be present, rotating my hand unnaturally. Ideally, I would like to use my entire hand hand rather than a single finger. Here's the location of my implant now:
The yellow dot shows the approximate location of my implant.
I think a quite favorable result could be achieved by using 12 total implants, like so:
At this point, however, I don't think that this is a good idea. Since my first implant has healed at a depth more shallow than I originally intended, it can be felt by pressing on my finger. Certain activities, such as gripping objects or playing foosball (as I discovered), can easily stress and cause pain and injury to the area. While it's not a big deal for a single finger, as I instinctively favor my other fingers now, a full array of these could pose quite a problem during day to day activities. Also, there is the question of polarity and orientation. There are no markings on the magnets to show their orientation (through playing with a compass I determined mine is South side out.) For an effective array, I would think that the magnets should all be oriented in the same way, which could be quite difficult to ensure during the implantation process. Something to start thinking about, at very least.
I'll continue to monitor the existing implant, and perhaps get two or three more in the near future, but a full hand project is still a ways off. On a related note, I'm receiving a set of significantly larger, more powerful, Parylene coated magnetic cylinders. I hope to implant one to see the effects of a more powerful magnet.
