Summary:In the Pb(Zr,Ti)O3/Pb(Zr,Ti)O3 sol-gel composite, the influence of humidity and the influence of atmosphere during poling treatment were investigated. There were three atmospheric conditions to be surveyed. There are three states: a high humidity state where the atmosphere is not controlled, a humidity control state by injecting nitrogen gas, and a humidity control state by injecting dry air. When poling in a high humidity condition where the atmosphere is not controlled, the piezoelectric constant d33 was confirmed to be as small as a number [pC/N]. On the other hand, when the poling was performed while the humidity was controlled by injecting nitrogen gas or dry air, a relatively large value of several tens [pC/N] was confirmed. Also, the ultrasonic response of these samples was measured. As a result, it was confirmed that the ultrasonic response was clearer when the humidity was controlled by injecting nitrogen gas or dry air than when the poling was performed in a high humidity state where the atmosphere was not controlled.
