An intelligent electronic capsulemicro system which can automatily identify gastric occult blood（GOB）information is designed.This system utilizes non-invasive deglutible capsule to automatically identify the OB information

transmitts detection result to the external device which can display the detection result and auto-matically identify OB status by template matching algorithm.In vitro experiments is carried to testify the system.Experimental results indicates that the effective detection concentration range of the system is 6

1

800 mg/L and the system can auto-matically emit alarm.With simplicity and easy operation

this system provides a new method for the screening of early-stage gastric cancer.
