摘　　要：介绍了可以在无创条件下检测消化道压力和温度参数的电子胶囊的标定与检测结果。采用硬件补偿解决了扩散硅压力传感器的温漂问题;通过标定实验得到了此装置关于压力和温度的标定曲线以及压力输出值和温度的相关性;临床试验证明了这种电子胶囊优良的工作性能和在消化道功能性疾病的诊断、治疗和预防方面的深远意义。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.
