| Abstract: | Detecting and locating is the critical question of diagnosis and treating for the hemorrhagic focus of digestive tract. A non-invasive method based on the electronic micro-system is presented for solving this question. And the hemoglobin sensor is developed and examined by the experiments. The result shows that the sensor is of high sensitivity to hemoglobin, and the output has linear relation with the concentration of hemoglobin. |
