Temperature sensing fabric |
摘要 |
A blanket or article of wearing apparel for a subject such as an infant. A fiber optic temperature sensing element is integrated into the fabric by a process such as weaving. The temperature sensing element is a optic fiber having inscribed therein one or more fiber Bragg grating sensors such that a light is introduced into the optic fiber and that light directed onto the subject at a grating interface. A return light signal is received, either by a reflectance mode or a transmission mode, where the return light signal has a wavelength shift indicative of the temperature of the subject by Bragg resonant effect. Higher temperature sensitivity is obtained with a metal material of a high thermal expansion coefficient that is coated around the fiber sensor cladding.
