“…Intrusive schemes to increase the sensitivity, bends [ 68 ], plus the cladding removal and partially polished core [ 69 ], can be easily done on POF fibres. An application for fuel-level measurements in paramotoring and powered paragliding is reported in [ 70 ], where the stripped POF liquid level gauges with different shapes are proposed with sensitivities at reception of 0.5 V per bend without the need of partially removing the fibre core.…”

We report on recent advances in the use of inexpensive polymer optical fibres (POFs) for sensing applications in avionics. The sensors analysed in this manuscript take advantage of the unique properties of polymers, such as high flexibility, elasticity, and sensitivity, and they range from strain, elongation, and vibration interrogators to level and temperature meters, leading to cost-effective techniques for structural health monitoring in aircraft structures. We also highlight recent power-supply methods using Power-over-POF in order to feed sensors remotely, and we discuss the constraints imposed by connectors on the performance of POF networks in aircrafts.

“…Sensors based on intensity variation also have significant advantages in terms of implementation and signal processing. They are used for measuring temperature using macro-bends [ 24 ] or liquid level [ 25 ] as well as healthcare applications [ 26 ], including plantar pressure measurements. To avoid errors induced by undesired power fluctuations, different self-reference techniques are proposed in the literature such as those described in [ 27 ] by using wavelength division multiplexing.…”

The proper measurement of plantar pressure during gait is critical for the clinical diagnosis of foot problems. Force platforms and wearable devices have been developed to study gait patterns during walking or running. However, these devices are often expensive, cumbersome, or have boundary constraints that limit the participant’s motions. Recent advancements in the quality of plastic optical fiber (POF) have made it possible to manufacture a low-cost bend sensor with a novel design for use in plantar pressure monitoring. An intensity-based POF bend sensor is not only lightweight, non-invasive, and easy to construct, but it also produces a signal that requires almost no processing. In this work, we have designed, fabricated, and characterized a novel intensity POF sensor to detect the force applied by the human foot and measure the gait pattern. The sensors were put through a series of dynamic and static tests to determine their measurement range, sensitivity, and linearity, and their response was compared to that of two different commercial force sensors, including piezo resistive sensors and a clinical force platform. The results suggest that this novel POF bend sensor can be used in a wide range of applications, given its low cost and non-invasive nature. Feedback walking monitoring for ulcer prevention or sports performance could be just one of those applications.
