| Research Abstract |
The objective of the research is to develop a small instrumentation system for health monitoring of inaccessible structural members of large-scale structures. In this research, the proposal and verification of elemental technologies that composed the sensing device were carried out. The following were carried out through the numerical analysis and the verification experiments of the prototype system ; shape proposal and performance verification of piezoelectric dynamic strain sensor, proposal of signal processing circuit and improvement of measuring device at operating time, possibility verification of backup power supply by piezoelectric power generation, and proposal of wireless communication function of measurement result.
