摘要：
Combining ASIC and multiple microsensors low-power wireless electronic capsule was developed for the long-term monitoring of the entire human gastro-intestinal (GI) tract. To meet the system requirements, several low-power designs were used in the wireless electronic capsule. The capsule measured 11 × 22 mm including batteries (45mAh). The capsule system’s lifetime was 233 h, and it could meet the requirements of almost all clinical applications. A wireless electronic capsule, portable data recorder, and workstation comprised the human GI physiological parameters monitoring system. In this paper, this system was used in a clinical trial to compare colon peristaltic pressure between patients with constipation and healthy people.
