Ex vivo measurement of lumbar intervertebral disc pressure using fibre-Bragg gratings

Abstract Methods were developed to measure intervertebral disc pressure using optical fibre-Bragg gratings (FBGs). The FBG sensor was calibrated for hydrostatic pressure in a purpose-built apparatus and the average sensitivity was determined to be −5.7±0.085 pm/MPa (mean±SD). The average coefficient...
