So I recently got my flexNeXT, not implanted yet, and I tried out the range with my phone (moto g pro). I got 3-3.5cm initially which wasn’t enough to scan it through my hand…
So I remembered a discussion here where amal expained that he used a coil over an implant to reshape the field and get a better range. But what if I moved the coil over the nfc antenna to “focus the beam” ?
Well I tried it and so far I’m getting satisfying results: the range got up to 4-4.5cm which is enough to get consistent reads through my hand!!! yay!
Also I had this idea that it might have not worked initially because the coils were not parallel… well that improved as well. It seems like the angle doesn’t matter as much anymore.
I still have to try other shapes and sizes but so far this is an easy mod that fits inside my phone case and allows me to shine wherever I am
