Integration of fibre-optic sensors in smart textile composites: Design and fabrication

This paper is concerned with some of the critical issues that arise in integrating fibre-optic sensors into smart textile composites. They include measurement principles and the selection of fibre-optical sensors, with emphasis on fibre Bragg-grating sensors, and the reliability and measurement effectiveness of the fibre-grating sensors embedded in textile composites, Three indicators are defined for measurement effectiveness, The effects of the coating modulus, host modulus, and radial and lengthwise positions on the maximum error, fibre-host strain ratio, and the:EPR-PR ratio are presented with reference to numerical-simulation results.
