In view of this, a volume-compact, easily-connected wireless strain collector is proposed in this paper. The collector modulates the differential strain signal by half-bridge and precise instrumentation amplifier, and employs an up-to-date RF (radio frequency) system (CC2530) on chip to realize digitalization for analog voltage signal and wireless transmission. The wireless sensor nodes based on TI’s Z-stack protocol possess high performances of network self-organization and network self-healing, and support low power consumption in wireless transmission by sleep mode. %U http://ckyyb.crsri.cn/EN/10.3969/j.issn.1001-5485.2014.07.024
