제안 방법
- In addition, the change in electrical characteristics was measured using the same method after annealing of 3D printing FBS in a constant temperature oven, allowing comparative analysis o the characteristics before and after annealing.
- The glass transition temperature (Tg) and crystallization temperature of the conductive PLA filament, which was used as an electrode of the bending sensor, were measured using a differential scanning calorimeter (DSC) to determine the appropriate temperature for annealing of the FBS. The measurement results were: PLA and carbon block’s Tg were approximately 62℃ and 880℃, respectively, and the PLA crystallization temperature was approximately 120℃.
- This study manufactured an FBS using FDM 3D printing and verified its applicability through experiments on changes in electric resistance against bending displacement. In addition, this study found that the electrode stability according to the 3D printing bending sensor design acted as an important variable to sensor sensing capability.
- This study produces a flexible bending sensor (FBS) that can be produced easily and facilitate intuitive judgment, using FDM 3D printing, and its performance is discussed. This will contribute to the promotion of FDM 3D printing use, departing from the simple structure production by expanding the utilization field of FDM 3D printing into various application areas including electronics and controls.
- However, these printing processes have the following drawbacks: complex processes that are not yet familiar to the public, high production cost, and limitation of size and shape. Thus, this study aims to produce an FED with a simple process and low production cost using a fused deposition modeling (FDM) three-dimensional (3D) printer, which is widely distributed to the public, and analyze its characteristics.
- To evaluate the characteristics according to the displacement of 3D printing FBS, the change in electric resistance was measured in real time while applying 10, 20, and 30% increase in bending displacement followed by 5-sec. stay and returning-back using a programmable logic controller (PLC), which was conducted five times, respectively, after fixing the bending sensor at the single-axis actuator.

- Thus, the annealing temperature was set to 120℃. The measurement equipment used was DSC200F3 manufactured by NETZSCH[7-8] .
