Objective： To design a sensing system for temperature detection and provide new surveillance measure. Methods： This system is composed of homemade demodulation instrument, software systems and display components. It conducted human simulation experiment by selection of packaging materials from a large number of experiments. Results： The result of medical monitor is better than mercury thermometer and electronic thermometers. The response time is shorter and higher sensitivity and accuracy under strong magnetic and acid conditions. Conclusion： It is reliable and viable that using Fiber Bragg grating on the temperature of the human body in medical field. It can set up local area networks for collecting and surveillance to medical departments. Therefore, it is worth to be as a new measure for further development.
