Abstract

In the previous report, we presented a self-powered digital system for vibration control. The self-powered system automatically measures the displacement of vibrating structure and digitally calculates the vibration state. Then it regulates its electric switches and achieves effective vibration suppression. Especially, it harvests electrical energy from structural vibration and utilizes the energy for activating itself. Some experiments with the self-powered digital system were reported in the previous report, which showed good results only in the steady-state condition. In this note, we demonstrate how the system works in the transient-state. These experiments clearly show the processor's transition between the wake-up and the sleep modes according to the vibration amplitude.
