유연성 탄소나노튜브 센서 기반의 구조물 건전성 감시를 위한 스트레인 발생 위치 추정 시스템

Abstract

In this study, a carbon nanotube (CNT) flexible strain sensor (CFSS) was fabricated with CNT based rubber composite for the strain sensing of structural health monitoring (SHM). The CFSS is a biomimetic flexible continuous strain sensor by means of piezoresistivity in CNT/EPDM (Ethylene Propylene Diene M-class) composite. For the application of the CFSS of SHM, an artificial neuron network system (ANS) was developed using an array of CFSS for a signal processing system of the sensor and applied to a flexible membrane. Moreover, a strain positioning algorithm (SPA) was developed to find the localized strain information of ANS in Labview environments.
