Collecting Sensor for Knee Controlling Muscle Movement Based on PVDF

摘要:

针对膝关节运动过程中控制肌群的运动信息的采集问题,文章设计了多种PVDF压电传感器的悬臂悬臂梁结构,利用传感器采集到的压电信息获取控制肌群的运动信息,并通过软件建模仿真和实验对比测试找到了最优悬臂梁结构设计为圆形简支悬臂梁结构,同时测试了传感器的性能；测试结果显示设计的PVDF压电传感器表现优越,可用于实际的信息采集。

Abstract:

In order to collect full piezoelectric data of controlling muscle during the knee movement, we developed a cantilever structure for various PVDF piezoelectric sensors, found optimal cantilever structure through software modeling, simulation and comparative experiments, which is circle simply-supported cantilever, then tested the performance of the sensor. It is showed the performance of PVDF piezoelectric sensor is excellent, which can be used for actual data collection.
