Abstract

Currently, existing skeletal sensors suffer from a 1-D detection, complex detection systems, and low detection sensitivity. In this article, a skeletal sensor with 2-D detection is proposed. The sensor consists of a substructure and detection elements. The substructure is composed of a negative Poisson’s ratio structure to increase sensor sensitivity. The detection element is composed of magnetostrictive material 2826 MB. Helmholtz coils and planar coils are used for reducing the detection complexity. A theoretical model of the interaction between the underlying structure and the magnetostrictive material is established. The sensor prototype is processed. Experimental platforms are set up for comprehensive testing of the sensor. Experimental results show that the sensor can perform 2-D force detection; it has a sensitivity up to 0.0381 mV/N and 0.6748 mV/N

具有二维检测能力的骨骼传感器

目前，现有的骨骼传感器存在一维检测、检测系统复杂、检测灵敏度低等问题。本文提出了一种具有二维检测功能的骨骼传感器。该传感器由子结构和检测元件组成。子结构采用负泊松比结构，提高了传感器的灵敏度。检测元件采用2826mb磁致伸缩材料，采用亥姆霍兹线圈和平面线圈，降低了检测复杂度。建立了底层结构与磁致伸缩材料相互作用的理论模型。对传感器样机进行处理。搭建实验平台，对传感器进行综合测试。实验结果表明，该传感器可以进行二维力检测；其灵敏度可达0.0381 mV/N和0.6748 mV/N $\cdot $ m，最大迟滞误差仅为2.659%，其最大负载为4.849 kN和48.14 N $\cdot $ m，传感器的最大负载完全满足人们日常生活的需要。传感器系统不需要复杂的操作。综上所述，该传感器很好地解决了目前骨骼传感器所面临的问题，在未来的骨骼研究中具有潜在的应用前景。
