“…Respiratory movement has an effect on Fiber Bragg grating (FBG) sensors, and several organs (e.g. ; lungs, liver, pancreas) may exert strain on the grating due to breathing-induced movement [ 47 ], as shown in Figure 1 . Smart textiles based on optical fiber sensors have shown promising results in respiratory monitoring and magnetic resonance (MR) environmental applications.…”

Malignant tumors have become one of the serious public health problems in human safety and health, among which the chest and abdomen diseases account for the largest proportion. Early diagnosis and treatment can effectively improve the survival rate of patients. However, respiratory motion in the chest and abdomen can lead to uncertainty in the shape, volume, and location of the tumor, making treatment of the chest and abdomen difficult. Therefore, compensation for respiratory motion is very important in clinical treatment. The purpose of this review was to discuss the research and development of respiratory movement monitoring and prediction in thoracic and abdominal surgery, as well as introduce the current research status. The integration of modern respiratory motion compensation technology with advanced sensor detection technology, medical-image-guided therapy, and artificial intelligence technology is discussed and analyzed. The future research direction of intraoperative thoracic and abdominal respiratory motion compensation should be non-invasive, non-contact, use a low dose, and involve intelligent development. The complexity of the surgical environment, the constraints on the accuracy of existing image guidance devices, and the latency of data transmission are all present technical challenges.

“…The FFT on the stray flux revealed a significant difference in spectral content, but also a consistency in these differences. For instance, when the motor was run at odd frequencies (5, 15, and 25 Hz), the stray flux under the broken rotor condition consistently showed a significant variation in its time varying amplitude, compared to the variations observed when the motor was run at even frequencies (10,20,and 30 Hz). This behavior may have been due to the forced vibration characteristics of the motor at odd frequencies compared to even frequencies, which would require vibration analysis, which is beyond the scope of this work.…”

Multiple techniques continue to be simultaneously utilized in the condition monitoring and fault detection of electric machines, as there is still no single technique that provides an all-round solution to fault finding in these machines. Having various machine fault-detection techniques is useful in allowing the ability to combine two or more in a manner that will provide a more comprehensive application-dependent condition-monitoring solution; especially, given the increasing role these machines are expected to play in man’s transition to a more sustainable environment, where many more electric machines will be required. This paper presents a novel non-invasive optical fiber using a stray flux technique for the condition monitoring and fault detection of induction machines. A giant magnetostrictive transducer, made of terfenol-D, was bonded onto a fiber Bragg grating, to form a composite FBG-T sensor, which utilizes the machines’ stray flux to determine the internal condition of the machine. Three machine conditions were investigated: healthy, broken rotor, and short circuit inter-turn fault. A tri-axial auto-data-logging flux meter was used to obtain stray magnetic flux measurements, and the numerical results obtained with LabView were analyzed in MATLAB. The optimal positioning and sensitivity of the FBG-T sensor were found to be transverse and 19.3810 pm/μT, respectively. The experimental results showed that the FBG-T sensor accurately distinguished each of the three machine conditions using a different order of magnitude of Bragg wavelength shifts, with the most severe fault reaching wavelength shifts of hundreds of picometres (pm) compared to the healthy and broken rotor conditions, which were in the low-to-mid-hundred and high-hundred picometre (pm) range, respectively. A fast Fourier transform (FFT) analysis, performed on the measured stray flux, revealed that the spectral content of the stray flux affected the magnetostrictive behavior of the magnetic dipoles of the terfenol-D transducer, which translated into strain on the fiber gratings.

“…Because several organs can strain the gratings due to movements caused by breathing, careful signal processing is required to mitigate measurement errors. 20) Moreover, these methods still require careful positioning of the thermal probes. Various temperature monitoring approaches use MRI signals.…”

In this study, an optical fiber probe with an extremely short integrated temperature sensor for high-power laser ablation was proposed and successfully fabricated. Both optical mode and wavelength multiplication were performed simultaneously using a double-clad fiber with a wavelength-division multiplication technique. The wavelength shift with temperature showed a linear relationship with a sensitivity of 10 pm/°C. High-power laser irradiation of 1000 mW or more using multimode transmission and fine temperature monitoring using single-mode transmission were performed simultaneously with a system response time of a few seconds. The laser wavelength selection and power variation can increase the variability of the heating region required for medical applications.
