The structure and mechanics model of thick film pressare sensor

traditional non-linear calibration’s methods and the theory of non-linear calibration with artifical neural network（ANN）are introduced.The model of thick-film pressure sensor’s non-linear calibration with BP neural network is discussed

and the program is emulated by ANN toolbox in MATLAB.The result indicates that the non-linear calibration of elasticity strain and pressure in the mothed can decrease 2 magnitude of the standard error and sensor’s non-linear calibration is effectively actualized.
