초록
본 논문은 충격 센서로써 압전 페인트 센서를 사용해 구조물 건전성 모니터링을 수행하였다. 본 연구에적용된 압전 페인트는 페인트 형태의 압전 재료로 물체에 얇게 코팅할 수 있고, 추가적인 외부 전원 필요 없이 충격 센서로 사용할 수 있다는 장점을 지닌다. 본 논문에서는 복합재 시편에 압전 페인트 센서를 네 부분으로 구분하여 도포한 후 충격 실험을 수행하였다. 압전 페인트 센서의 감도는 충격 힘에 따른 출력 전압을 측정하여 구하였고, 감도 측정과 더불어, 시편에 충격이 가해진 경우 압전 페인트 센서의 출력 신호를 비교하여 충격 위치도 추정하였다
Abstract
This paper presents a structural health monitoring method using piezoelectric paint sensor designed foran impact sensor. The piezoelectric paint sensor can be flexibly deposited onto most structural surfaces in a thin formof the paint, and measure impact signals without any external device such as a power amplifier. In this study, acomposite plate having four zones coated with piezoelectric paint was used for impact monitoring test. The sensitivityof the piezoelectric paint sensor was obtained by measuring the output voltages against the impact force. In additionto the sensitivity measurement, the impact position has been also estimated by comparing the output signals of thepaint sensors when the impact occurs on the specimen.
