我们开发了一种新型弯曲传感器，用于液压驱动主动导管的方向控制。一开始，我们提出并制造了能够安装在直径为3.0mm的有源导管中的弯曲传感器。多模光纤表面上制作的一些孔根据曲率将光扩散到光纤内部。通过弯曲传感器测量光量表明弯曲角度已得到验证。此外，我们成功地利用弯曲传感器实现了液压驱动主动导管，并在控制过程中实时测量弯曲角度。这种简单的弯曲传感器因其安全性、微小尺寸和简单性而满足医疗设备和遥感等许多领域的需求。
We developed a novel bending sensor for orientation control of hydraulic pressure driven active catheter. At beginning, we proposed and fabricated the bending sensor which was able to be included in the active catheter that was 3.0mm diameter. Some holes fabricated on the surface of a multimode optical fiber diffused light the inside of the fiber depending on curvatures. Measuring amount of light through the bending sensor indicated the bending angle was verified. In addition, we succeeded hydraulic pressure driven active catheter with the bending sensor and measured real time bending angle during control. This simple bending sensor satisfies for many fields such as medical devices and remote sensing because of its safety, microsize and simplicity.
