Optical fiber curvature sensor for measuring body motion and its adhesive method

Abstract

An adhesive method for an optical fiber curvature sensor results in a sensor having improved sensitivity for measuring body motions such as motions of fingers, arms, or legs, and in particular that is capable of measuring both a curving direction and degree of curvature of a subject simultaneously, even for variable surface areas such as those of the waist or shoulders. The method is carried out by adhering an optical fiber to a subject in a curved state.
