“…They also calibrated the sensor's temperature properties, and the sensitivity was attained at 32 pm/ • C, which means that the tapered CTMCF can eliminate the cross-sensitivity to temperature. Song also demonstrated this characteristic of CTMCF via experimental verification [89]. Xiang utilized the CO 2 laser method to fabricate an LPG from a twisted MCF, which also demonstrated low-temperature cross-sensitivity [29].…”

With an increase in the volume of information exchange and perception, the demands for intelligent, miniaturized, and integrated optical devices for information acquisition are also increasing. As the core component of optical networks for transmitting information, further optimization of their structural characteristics to generate richer optical characteristics and apply them to information exchange and optical field control has become a key research hotspot. The introduction of chiral twist characteristics has led to new phenomena and applications in optical field transmission and the transformation of traditional optical fibers or microstructured optical fibers (MOF). Therefore, this review mainly begins with the principle of chiral optical fibers, introduces their preparation and latest application scenarios, and finally discusses their potential future development prospects.

“…This model included a material constant, denoted as 'G' in [24], and it was calculated experimentally. Such an approach has limitations when it comes to representing the twist, considering the non-linear nature of the strain vs. twist angle [74]. In addition, testing bending along with the twist requires calculating the material constant for each curvature.…”

Piecewise constant curvature soft actuators can generate various types of movements. These actuators can undergo extension, bending, rotation, twist, or a combination of these. Proprioceptive sensing provides the ability to track their movement or estimate their state in 3D space. Several proprioceptive sensing solutions were developed using soft strain sensors. However, current mathematical models are only capable of modelling the length of the soft sensors when they are attached to actuators subjected to extension, bending, and rotation movements. Furthermore, these models are limited to modelling straight sensors and incapable of modelling spiral sensors. In this study, for both the spiral and straight sensors, we utilise concepts in geodesics and covering spaces to present a mathematical length model that includes twist. This study is limited to the Piecewise constant curvature actuators and demonstrates, among other things, the advantages of our model and the accuracy when including and excluding twist. We verify the model by comparing the results to a finite element analysis. This analysis involves multiple simulation scenarios designed specifically for the verification process. Finally, we validate the theoretical results with previously published experimental results. Then, we discuss the limitations and possible applications of our model using examples from the literature.
