This paper reports a fully self-powered wireless node for sensor-network that monitors the kinetic amount of mechanical vibration. The self powered sensing function is enabled by a newly developed energy-harvester that can generate considerable electric power only when the monitored amplitude of the vibratory acceleration reaches or exceeds a pre-set threshold. The generated electric-energy can be accumulated over time into stored charge to represent the converted kinetic-energy amount of the… CONTINUE READING
