Abstract
Aimed at a self-powered real-time pipe-wall-thinning monitoring system, a piezoelectric vibration energy harvesting device is installed on a pipe in a pipeline system with internal fluid flow and its plausibility as a power source of a sensor node is checked experimentally. To this end, a bimorph cantilevered plate with two piezoelectric single crystal layers is designed to a measured excitation frequency of 154 Hz, the average output power of which is measured to be around 30 μW/(m/sSUP2/SUP)SUP2/SUP in the laboratory test using a electrodynamic shaker. To clamp the designed bimorph cantilevered plate on a vibrating curved surface of a pipe with little effects on its modal properties, a band-type mounting scheme is proposed in this work. It is experimentally shown that piezoelectric vibration energy harvesting can be an alternative to battery-powered solutions, though the reliability issue still remains.
