利用单根多壁碳纳米管（MWNT）-玻璃纤维监测复合材料中微裂纹的萌生和扩展，为材料断裂的早期检测提供了一种预警系统。基于纳米管桥跨微裂纹在外部应变或热膨胀下的连接/断开，进一步构造了机电微动开关。
A single multiwalled carbon nanotube (MWNT)-glass fiber is used to monitor the initiation and growth of microcracks in composites, which provides an early warning system to detect fracture in materials. An electromechanical microswitch is further conStructed based on the connecting/breaking of the nanotube bridges across microcracks under external strain or thermal expansion.
