应变测量是智能材料结构实现其健康监测、振动控制和形状控制等功能的基础。本文介绍智能材料结构中新近发展起来的几种采用压电传感元件的应变测量技术，其中包括压电应变片技术、自传感驱动技术、模态传感与空域滤波技术、分布式传感器阵列以及自屏蔽措施等。 Strain gauging is the foundation on which intelligent material structures perform their health monitoring, vibration control and shape control functions. This paper introduces several newly developed strain sensing techniques using piezoelectric sensing elements in smart material structures, including piezoelectric strain gauge technology, self-sensing drive technology, modal sensing and spatial filtering, distributed sensor array And self-shielding measures.
