Outline of Final Research Achievements |
In this study, we have developed a wireless sensor for monitoring of heath condition of infrastructures such as bridges, tunnels and transmission line towers. To realize the wireless sensor which works without batteries, we have developed a novel chaotic-vibration energy harvester which can harvest powers from the vibration of the infrastructures with wideband spectrum. It is experimentally shown that the energy harvester can drive the wireless sensor from the excited vibration whose amplitude is about 0.1G.
