In this paper, some recent advances on research, development and implementation of smart sensor networks and health monitoring systems for civil infrastructures in China's Mainland, especially in Harbin Institute of Technology (HIT), P. R. China, are summarized. The main contents include smart sensors such as optical fiber Bragg grating (OF-BG) and polyvinylidene fluoride (PVDF) sensors, fatigue life gauges, shape memory alloy (SMA) , self-sensing mortar and carbon fiber reinforced polymer ( CFRP), wireless sensor networks and their integrated systems and implementations in practical infrastructures such as offshore platform structures, hydraulic engineering structures, large span bridges and large space structures. Finally, the relative research projects supported by the national foundation agencies of China are briefly introduced and some issues to be further researched are pointed out.
