GI & Pediatric GI Physicians - Ingestible Tech & Accidental Ingestion

Looking for sources: I'm writing a lighthearted story about ingestible technology. Many people may be aware of the harms of children swallowing batteries or be aware of accidentally swallowing things like Airpods (a story recently went viral on Instagram). However, most folks have never heard of technology that is actually designed to be swallowed and how it is used in medicine and research. If you know someone I should talk to who has expertise in ingestible technology, has a story about an accidental ingestion, or experience in GI or pediatric GI medicine, please let me know!
