PIEZOELECTRIC ELEMENT AND ACTUATOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240114796 titled 'PIEZOELECTRIC ELEMENT AND ACTUATOR
Simplified Explanation
The piezoelectric element described in the patent application consists of a substrate with multiple layers of electrodes and piezoelectric films containing perovskite-type oxides. The polarization-electric field hysteresis of the films is measured to determine their properties.
- The piezoelectric element includes a substrate, first electrode, first piezoelectric film, second electrode, second piezoelectric film, and third electrode.
- Both the first and second piezoelectric films contain perovskite-type oxides with pb, zr, ti, and m as main components.
- The pb composition ratios in the perovskite-type oxides of the first and second films are different.
- The polarization-electric field hysteresis of the films is measured with different electrode configurations.
