Micro Multi-Information Acquiring System for G.I. Tract Based on Biotelemetry

In this paper, a micro electronic device was presented, which can acquire multiple information of gastrointestinal tract, for instances cavity pressure, temperature and bleeding condition et al. Biotelemetry was used to communicate between internal and external body. For strict restriction of space and power, the low consumption circuits were elaborately designed. Some experiments proved the good performance of this micro device. The multi- information acquiring system is of much significance for gastrointestinal disease diagnose.
