광섬유 굽힘 손실을 이용한 직물 기반의 광섬유 촉각센서 개발

Abstract

In this paper the tactile sensor system based on the bending loss of optical fiber sensor is presented. The sensor array was designed with fabric structure. The optical measuring system was composed of LED for light source and CCD camera for the signal light detector. Performance of this tactile sensor system was evaluated in various environments and compared with Harmons design criteria. The result shows that load range is 3 g ~ 100 g, resolution is 1.5 g, hysteresis error is 1.5%. The response linearity is good and flexibility of sensor array is excellent.
