I would be HIGHLY against this idea of an implant, it feels far too distopian (and I'd argue possibly against a person's right to their body). I'm not in the medical field but I'm sure there's many places such as "closish" to an artery that trained doctors would have no issues getting at but a random joe with a switch blade may have issues with. I'd figure just detecting the temperature change and alerting the authorities would be easier though, then you can place it just like a standard animal tracker, e.g. a needle in their arm/back.
