摘　　要：介绍了一种利用压电双晶片的逆压电效应来测量眼压的方法及其装置。该方法建立了流过晶片的电流和眼球内部压强的关系,通过检测的电流值来测量眼压值。实验表明,该方法操作简便,可行性较好,有一定的临床应用前景。该文还给出了实验结果和误差分析。A method taking the effect of the anti-piezoelectricity of the piezoelectric bimorphs to measure intraocular pressure was proposed. This method established relationships between current washing through the bimorphs and intraocular pressure. Then the result of intraocular pressure was valued by the measured current. The experiment showed that it was practicable and simple for operation and with some application prospect in clinic. Experiment results and error analysis were also given in the paper.
