From wearables to swallowables: Engineers create GPS-like smart pills with AI

Imagine finding your location without GPS. Now apply this to tracking an item in the body. This has been the challenge with tracking “smart” pills—pills equipped with smart sensors–once swallowed. At the USC Viterbi School of Engineering, innovations in wearable electronics and AI have led to the development of ingestible sensors that not only detect stomach gases but also provide real-time location tracking.
