[Development and applications of a gastrointestinal monitoring microsystem based on the smart capsule].
A newly-developed gastrointestinal (GI) monitoring system based on a smart capsule is presented in the paper. The unprecedented 130-200 hours battery life and smaller size (10 mm x 20 mm) allows the physician to get total pan-colonic measurements of high-amplitude propagating contractions (HAPCs). To test the in vivo performance of the monitoring system, 15 healthy volunteers and 10 patients with slow transportation constipation (STC) participate in this study. The average of HAPCs occurred in patients is significantly lower than in volunteers (12.4 +/- 3.3 vs. 18.5 +/- 3.7 p = 0.013). The system provides a useful tool for STC diagnosis and treatments of patients.
