Scientists are increasingly recognizing the GI tract as essential to overall health, not just for digestion, but also for producing hormones, immune cells, and neurotransmitters that affect mood and brain function.

This makes the GI tract a rich source of biomarkers for detecting and managing disease. However, current methods to analyze these biomarkers, like fecal tests and biopsies, are invasive and limited.

To address this, Caltech engineers have developed PillTrek, a tiny, ingestible smart capsule that can wirelessly measure pH, temperature, and various biomarkers such as glucose and serotonin. It uses low-power electronics and interchangeable sensors, making it a flexible and scalable tool for gut health monitoring.

The capsule, smaller than existing endoscopy pills, represents a major advancement in real-time, non-invasive GI tract analysis.
