光纤传感器是研究温度、应变和压力等物理特性的强大工具。这样的特性使这些传感器在包括生物医学应用在内的许多应用中都很有趣。光纤传感器也是利用光频域反射原理进行分布式传感的一个很好的平台。分布式传感越来越多地被用来实现高分辨率的测量和在小尺度上绘制生物材料的物理属性，从而获得特定感兴趣区域的2D和3D映射。这项工作旨在建立和研究一种基于分布式光纤传感技术的二维传感地毯，以映射施加在地毯上的局部压力。这种二维映射是通过在柔软的硅胶地毯中嵌入单模光纤来实现的。纤维已经弯曲并排列成以几条平行线为特征的特定构型。通过比较分析，研究了不同的纤维固定方法，以更好地表征地毯并实现更精确的响应。当纤维完全嵌入到有机硅地毯中时，检测到最佳的压力敏感系数(0.373 pm/kpa或考虑我们的设置为1.165 nm/kg)。本文论证了在分辨率为2 mm×2 mm的表面上映射2D分布压力的可能性。调查表面为2厘米乘6厘米，包含310个感应点。通过在地毯不同部分上测试结果的一致性，对选择几个优先位置的传感地毯进行了验证。
Fiber-optic sensors are a powerful tool to investigate physical properties like temperature, strain, and pressure. Such properties make these sensors interesting for many applications including biomedical applications. Fiber sensors are also a great platform for distributed sensing by using the principles of optical frequency domain reflectometry. Distributed sensing is becoming more and more used to achieve high-resolution measurements and to map physical properties of biomaterials at small scale, thus obtaining 2D and 3D mapping of a particular area of interest. This work aims at building and investigating a 2D sensing carpet based on a distributed fiber sensing technique, to map local pressure applied to the carpet. The two-dimensional mapping is obtained by embedding a single-mode optical fiber inside a soft silicone carpet. The fiber has been bent and arranged in a specific configuration characterized by several parallel lines. Different fiber fixation methods have been investigated by means of a comparative analysis to perform better characterization and to achieve a more precise response of the carpet. The best pressure sensitivity coefficient (0.373 pm/kPa or considering our setup 1.165 nm/kg) was detected when the fiber was fully embedded inside the silicone carpet. This paper demonstrates the possibility of mapping a 2D distributed pressure over a surface with a resolution of 2 mm by 2 mm. The surface of investigation is 2 cm by 6 cm, containing 310 sensing points. The sensing carpet has been validated selecting several preferential positions, by testing the consistency of the results over different portions of the carpet.
