“…Hence, the controlled but possible masticatory activity of the patient, which is normal after ORIF contrary to conservative treatment [ 4 ], contributes to bone healing. These interfragmentary movements are crucial for the complex process of consolidating fracture [ 69 ]. Reasoning in this way, one can justify the favorable reduction in relative fixation stiffness by using magnesium screws (Young’s modulus 44 GPa, Table 3 ) in comparison with classical titanium screws having a higher elastic modulus.…”

For some years now, fixation devices created with resorbable magnesium alloys for the mandibular head have been clinically available and are beginning to be used. It is thus valuable to evaluate the quality of unions in these cases. The aim of this study was radiological comparison of magnesium versus titanium open reduction and rigid fixations in the mandible condylar head. Thirty-one patients were treated for fractures of the mandibular head with magnesium WE43 alloy headless compression screws (diameter 2.3 mm) and, as a reference group, 29 patients were included with similar construction titanium screws (diameter 1.8 mm). The 12-month results of the treatment were evaluated by the texture analysis of CT. Near similar treatment results were found with magnesium screws in traditional titanium fixation. Magnesium screws result in a higher density of the bone structure in the mandibular head. Conclusions: The quantitative evaluation of bone union after surgical treatment of mandibular head fracture with magnesium compression headless screws indicates that stable consolidation was achieved. Undoubtedly, the resorption process of the screws was found to be incomplete after 12 months, evidenced by a marked densification of the bone structure at the fracture site.

“…The distortion is reduced by 95% when four pins are fixed above the fracture, but the deformation is increased by about 112% when four pins are fixed above the fracture site. Through frequency analysis of FBG sensors, we can only measure this, according to Kalinowski et al [ 7 ]. In this study, Tavares et al discussed wheelchair pressure ulcers and designed a wheelchair.…”

“…Based on result obtained, it was observed that four pins below the fracture showed an increase in deformation of 112.8%, whereas four pins above fracture had a decrease in deformation of 95%. Thus, by this analysis fractured bone could be easily differentiated from system and healing process could be done [ 26 ]. In another context, we can see that Mishra et al proposed on Fiber Bragg Grating sensors for investigating in vitro spinal cord injuries.…”

Due to attractive application in the medical field, fiber Bragg grating sensor has become increasing attractive from past few decades for various strain sensing applications. FBG sensor has been used in many applications such as different surgical devices, vital sign detection devices, invasive surgery, heart rate, dental applications and biosensing application as wearable sensing devices. This paper reviews the 55 recent research articles published on fiber Bragg grating sensor for biomedical application used the qualitative, quantitative and experimental method to identify the recent advancement and challenges. In this study, particular focus is placed on applications for biomechanical devices, temperature monitors, respiratory monitors, and biosensing applications. Critical things, demands, and emerging trends for these sensing devices are also discussed in order to determine what will be needed for the next generation.

“…Socorro-Leranoz et al [15] report the development and characterization of parallel FBG to monitor the movements of the wrist and fingers of a hand, the system that can be used to monitor the positions of the hand or for the rehabilitation of patients suffering from neuromotor or post-stroke diseases. Kalinowski et al [16] used FBG sensors to measure the static and dynamic strain of the external fixation device used in patients who have suffered fractures in the lower limbs. In [17], the authors use four FBG sensors embedded in carbon fiber-reinforced polymer in a smart foot; the results of the FBG sensors are used in an adaptive fuzzy-proportional-integral-derivative (FPID) control strategy.…”

This article presents the development of a liquid-level sensor using fiber optic Bragg gratings (FBG). The sensor comprises a carbon-fiber-reinforced polymers (CFRP) diaphragm packaging an embedded FBG to measure strain. A mathematical analysis determines the FBG response to the pressure exerted by a liquid column over the packaged sensor. The experimental arrangement consists of an acrylic tube with a sensor at the bottom. FBG signals were acquired using a DI 410 optical interrogator manufactured by HBM. A finite element simulation with Ansys was performed to determine the most reposeful position from the FBG sensor. The experimental results show the analysis of eight repetitions of the water column ranging from 10 cm to 60 cm using 10 cm steps. The sensor showed a linear response, with a coefficient of determination of 0.999, and a sensitivity of 4.1 pm/cm; and the maximum standard deviation is 0.64 pm. Although water is used in the calibration process, other liquids could also be used, obtaining a different angular coefficient depending on the density of the liquid used.
