Design of Photo-Induced Biofeedback Fabric and Study of its Influence on Brain Wave

Abstract

Because of stress and sleeping obstacle for 21th century people, the purpose of this study is to design a home decorative fabric which has the function of releasing from stress and enhancing sleeping quality. The optical fiber were sewn on the surface of optical fabric in form of three kinds of curvature patterns. Guiding the LED light into the optical fiber, the light will emit out of the optical fiber and stimulate our visual system in order to change the form of brain wave. Afterwards, the EEG instrument was used to evaluate the function of stress relaxation of such fabrics. The results were shown that human’s brain wave can be changed from relaxed and sober status to shallow-sleeping status after the stimulation of light emitting from the optical fiber fabrics. For the effect of causing shallow-sleeping status, female is more significant than male. Therefore, the light stimulating visual system by using the optical fiber fabrics can change the form of brain wave and achieve the effect of stress relaxation.
