超低功耗事件驱动型微能量触发系统
Ultra-low Power Event-Driven Micro Energy Harvesting Trigger System
摘要
Abstract
In response to the problem of high leakage current during sleep and short working cycles in unmanned wireless sensor systems,an innovative ultra-low power event-driven micro energy harvesting trigger system is proposed.Compared to traditional systems,this new system introduces two working modules,feedback cut-off and mis-triggering detection,to improve the stability and reliability of the wireless sensor system.Experimental results show that when the micro-energy is collected from 2.4 GHz and 5.8 GHz hotspot signals from mobile phones,the rectifying antenna output signal triggers the switch module,allowing the commercial module to function normally.The feedback cut-off module achieves timed cut-off of the circuit,and the mis-triggering detection module detects and judges the mis-triggering signal on the input end,generating a feedback signal to turn off the switch module if the switch is accidentally closed.Power consumption testing re-sults show that when powered by a 5 V-4 440 mA·h lithium battery,the leakage current of the ultra-low power event-driven micro energy harvesting trigger system is less than 10 nA,and the overall power consumption is less than 50 nW,which is only 1%of the power con-sumption of existing micro-energy harvesting trigger systems.The system's operating cycle is extended from 76 days to approximately 93 days,and its lifespan is increased by about 21.7%,making it suitable for unmanned environments and optimizing the wireless sensor system.关键词
