摘　　要：本文以光寻址电位传感器为基础,研究具有EIS结构并列型半导体体液分析传感器。重点研究了背面照射时,偏置电压、光调制频率和光功率等对传感器光电压的影响,并给出优化条件。该传感器在优化测试条件下,对样品液中的pH(1～10pH范围)、pO_2(0.9～10ppm范围)和葡萄浓度(10^(-5)～10^(-2)M范围)具有灵敏响应特性。This papet studies parallel EIS type light addressable semiconductor humor analysis sensor based on light addressable potentiometric sensor. The eflFects of the bais voltage, light modulation frequencies and light radiation power on photovoltage for the sensor with backside illumination are studied mainly. The optimized result of these parameters is given. Good response characteristics were obtained when it was used in determination of the pH(1-10pH), pO2(0.9-10ppm) and concentration of glucose (10-5 ~ 10-2M) in sample liquid.
