A new layered sensor for simultaneous measurement of electromyography (EMG), mechanomyography (MMG) and oxygen consumption based on near-infrared spectroscopy (NIRS) at the same position of the muscle is presented. The proposed sensor is a layered structure of a thin stainless-steel electrode, a PVDF film with transparent electrodes and optical sensors. EMG, MMG and oxygen consumption based on NIRS are measured by the stainless-steel electrodes, PVDF film and optical sensors, respectively. Using the three types of data, muscular activity can be analyzed in more detail. Additionally, the proposed sensor system reduces the constraint of the sensors arranged on the skin in measurements at multiple points because three types of information, previously obtained with three types of general sensors, are detected by a pair of proposed sensors. In an experiment, simultaneous measurement of EMG, MMG and oxygen consumption via NIRS at the forearm was demonstrated using the proposed sensor under fluorescent light. The performance of the layered sensor was evaluated.
提出了一种新型分层传感器，用于在肌肉同一位置同时基于近红外光谱（NIRS）测量肌电图（EMG）、机械肌电图（MMG）和耗氧量。所提出的传感器是一种由薄不锈钢电极、带有透明电极的聚偏二氟乙烯（PVDF）薄膜和光学传感器组成的分层结构。基于NIRS的EMG、MMG和耗氧量分别由不锈钢电极、PVDF薄膜和光学传感器测量。利用这三种类型的数据，可以更详细地分析肌肉活动。此外，所提出的传感器系统减少了在多点测量中传感器布置在皮肤上的限制，因为一对所提出的传感器可以检测到以前用三种通用传感器获得的三种类型的信息。在一项实验中，使用所提出的传感器在荧光灯下展示了在前臂同时测量EMG、MMG和通过NIRS测量的耗氧量。对分层传感器的性能进行了评估。
