摘 要:A photonic sensor with radio frequency(RF)power detection for body pressure monitoring is *** sensor based on two fiber Bragg gratings(FBGs)can transfer the wavelength shift to the change of RF *** pressure can be measured by modulating and processing one single frequency RF *** theoretical analysis and experimental results of the photonic sensor are presented and *** pressure sensitivities are acquired with 2.62×10^(−5)mW/kPa at 2.14 GHz,2.46×10^(−5)mW/kPa at 2.21 GHz,2.81×10^(−5)mW/kPa at 2.37 GHz,and 3.02×10^(−5)mW/kPa at 2.45 GHz,***,the pressure measurements of pressed body parts are also obtained by the sensor.
