An AI-powered wearable system tracks the 3D movement of smart pills in the gut.

Scientists at the University of Southern California have developed an AI-powered system to track ingestible devices that monitor markers of disease in the gut. This system, which includes a wearable coil and optical gas-sensing membranes, can pinpoint the location of the device in the gut and measure levels of gases such as ammonia. The technology has potential applications in monitoring gastrointestinal health, identifying inflammation caused by Crohn's disease, and delivering drugs to specific regions of the gut. While improvements are still needed, the researchers are optimistic about the practicality of the system and plan to test it in pigs before human clinical trials. [Extracted from the article]
