| Research Abstract |
Recently, a wireless sensor node has been expected as one of important tools to assess the structural health of bridges. An attempt in this study is made to investigate an applicability of PZT for a power source of wireless sensor nodes. From laboratory experiments, it is observed that piezoelectric property depends on the magnitude of strain of the structure. As a result, it was found that PZT can be available as a power source of wireless sensor nodes if some requirements can be satisfied.
