在这项研究中，针对柔性内窥镜手术的应用，开发并演示了一种具有高抗温度和照度波动能力的管腔内压力传感器。该传感器装置专门设计用于嵌入内窥镜尖端。器件表面镀有0.1μm厚的Cr层，以防止内窥镜强光产生光电。另一方面，利用集成温度传感器成功地对压力信号的温度漂移进行了补偿。测得的压力分辨率为0.4mmHg，对应的压力误差为3.2mmHg。封装后的装置在模拟动物实验环境下成功运行，即使在pH1的酸性溶液中也成功演示了压力和温度的监测。
In this study, an intraluminal pressure sensor with high immunity against fluctuation of temperature and illuminance aimed at application of flexible endoscope operation has been developed and demonstrated. The sensor device was specially designed for embedment on the endoscope tip. A 0.1μm thick Cr layer was coated on the device surface to prevent photo-electronic generation caused by strong endoscope's light. On the other hand, compensation of temperature drift on pressure signal was successfully performed with integrated temperature sensor. Measured pressure resolution was 0.4mmHg, and the corresponding pressure error was 3.2mmHg. The packaged device was successfully operated under mimic environment of animal experiment, and monitoring of pressure and temperature was successfully demonstrated even in pH1 acid solution.
