Abstract

In this work, an appropriate analysis model of a precise foot sensor with low detection pressure capability under a low range of variation in the dimensional variables was proposed. With a simple two-dimensional model, it was found that a remarkably high error level sometimes occurred between the analysis and experimental results. In order to overcome the error and improve the performance, a three-dimensional model was introduced, and the detection pressure and sensor characteristics were compared with those of the experimental results, which showed its enhanced performance with less error and higher precision.

본 논문은 감도가 낮고 정밀한 족적센서의 특성에 대하여 연구한 논문이다. 이를 위하여 센서의 형상 변수 조절 범위를 낮게 선정하였다. 센서의 감도 해석으로 2차원 해석 모델을 사용할 경우 실험값과 비교한 결과 오차가 많이 나는 것을 확인하였다. 따라서 이 오차를 개선하기 위하여 3D 기반의 새로운 해석 모델을 적용시켜 재해석 하였고, 이를 실험값과 비교한 결과 오차가 개선되었음을 확인할 수 있었다.
