Abstract

In order to measure the important physiological parameters such as temperature, pressure and pH value, we developed a miniature, high precision, non-invasive and multi-sensor radiotelemetry system. The system comprises multi-sensor radiotelemetry capsule, data logger, location device and workstation. The radiotelemetry capsule can monitor the pH, pressure and temperature of the entire intestinal tract and send the data to the data logger outside the body through a wireless communication link. After the capsule is egested from the anus, further analysis of the physiological parameter data saved in the data logger can be performed via the special software installed at the workstation. Clinical experiments prove that the radiotelemetry system is non-invasive and reliable. Moreover it is found that the radiotelemetry system is an effective method to study intestine motility characteristics.
