Instead of pushing the finicky implant design, how much easier it would seem to merely wear a wristwatch with added functionality: short-range biotelemetry to an immobile modem-equipped device in a flat, or a belt-worn biotracker with cellular modem and GPS outdoors, periodically linking up to a tracking server cluster.
Using Li-cell driven (power good for a month at least) contactless sensors like MEMS accelerometers, photophlethysmography and photooxytometry etc.signals evaluated by a low power embedded, periodically bursting data via a cellular modem to a high-availability Linux system cluster with a GIS (all open source, of course) you can prototype such a design within months.
