Definitive confirmation of medication ingestion (gold standard)
Precise timestamp of medication administration
Can track physiological parameters (activity, rest patterns)
Eliminates adherence measurement ambiguity

Challenges and Considerations:

Higher cost than conventional tablets ($1,000-2,000 monthly for some formulations)
Privacy concerns about detailed ingestion and physiological monitoring
Patient acceptance varies; some find the technology intrusive
Requires patient to wear sensor patch and use smartphone app
Limited to specific medication formulations approved with embedded sensors
