| Outline of Final Research Achievements |
We developed two types of vibration sensors based on new operating principles for multi-point and continuous monitoring of deteriorated concrete structures. For the triboelectric nanogenerator-type vibration sensor, we developed a sensor applying the principle of frictional electrification by using stable gold nanowires as the electrodes of the element. By developing a technique to coat only the surface of the gold nanowires with an organic polymer, we demonstrated the possibility of mechanical operation-electrical signal conversion based on the principle of frictional electrification. In the resonant-type vibration sensor, we achieved high acceleration linearity and low cross axis sensitivity by adopting resonance phenomena as the operating principle of the vibration sensor. Furthermore, compared to conventional piezoelectric elements, we were able to obtain vibration information with extremely high signal purity.
