It has also been designed to dissolve into the body when no longer needed, sparing patients invasive surgery.

More likely, it will just remain a (hopefully) inert embedded implant. If it has active electronics, and thus semiconductors, I doubt e.g. silicon will dissolve.

Edit: care to refute?

I think the pacing/logic part is in the patch worn on the skin surface. From what I understand the rice grain part converts an optical signal it sends into an evoked potential.
