【Abstract】 The method to calibrate an electronic capsule is introduced,which can detect the press and temperature value of gastrointestinal(GI)track without any trauma.Hardware compensation is adopted to resolve the drift of diffuse silicon press sensor caused by temperature variation successfully.Through calibration experiments,the calibration curves of press and temperature were obtained as well as the dependence between the press output and temperature.Clinic experiments demonstrate the electronic capsule with good performance and far-reaching significant for diagnosis,therapy and prevention on some functional sickness of GI track.更多还原
