Yep, you could run an anonymization workload inside the OpenPCC compute node. We target inference as the "workload" but it's really just attested HTTP server where you can't see inside. So, in this case your client (the wearable) would send its data first through OpenPCC to a server that runs some anonymization process.

If it's possible to anonymize on the wearable, that would be simpler.

The challenge is what does the anonymizer "do" to be perfect?

As an aside, IMO homomorphic encryption (still) isn't ready...
