| Abstract: | In the paper,the aim is that combining numerical analysis with the data processing of the sensor.Fristly,it introduces the principle of stress sensor,testing＇s theory and the principle of curve fitting.What＇s more,there are some other introductions about the circuit testing of the sensor,then followed by the relationship about the input and output of the sensor.Experiment＇s results show that,on some extent,a linear relationship is found about stress sensor. |
