Paper Abstract
In recent years, unrestrained monitoring human posture and action is a field of increasing interest in the welfare of the
elderly and the sport-biomechanics. The scope is this study is that we develop a wearable sensing clothes, which can
detect entire body posture and motion using a hetero-core optic fiber sensor. This newly developed sensor can offers
several advantages such as the simplicity of structure and fabrication, the stable single mode based operation, the
temperature independent property, and the precise loss controllability on given macro bending. These properties are
suitable for implementing unrestrained wearable clothes. In this paper, for monitoring flexion of joint without the
disturbance of the rucks in the clothes, we proposed and fabricated the improved module structured in the joint ranging
0-90 degree. Additionally, in order to reduce the number of transmission line to be added due to monitoring the whole
body posture and motion, we tested that two hetero-core sensors which are tandem placed in a single transmission line
have been discriminated by the temporal differential of the optical loss. As a result, we have successfully demonstrated
that the wearable sensing clothes could monitor arm motion and human walking without restraint to human daily
behavior.
