摘要：
A textile comprising a pressure sensor, the pressure sensor comprising an optical fibre 102 with a transducer Fibre Bragg Grating (FBG) 107 embedded in a transducer patch 101 having a length of less than 10mm along the optical fibre 102. The transducer patch 101 being configured to cause longitudinal strain in the transducer FBG 107 in response to the transducer patch 101 being subject to a pressure load 110 on one of its faces； the longitudinal strain arising as a result of extension of the transducer patch 101 due to the Poisson effect. The textile preferably comprises a compression bandage, compression garment, sock, footwear, orthotic, mattress or seat. The transducer FBG 107 may further be provide in a system comprising a strain compensation FBG (127, Fig 4) and/or a temperature compensation FBG (117, Fig 4) for providing compensation for longitudinal forces and/or temperature artifacts experienced by the transducer FBG 107. A method of monitoring pressure applied to a user via the textile is also taught, and comprises, applying the textile to the body, using an optical interrogator to determine a Bragg wavelength of the transducer FBG and using a processor to determine the corresponding pressure load.
