PIEZOELECTRIC ELEMENT AND ACTUATOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240114801 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 a perovskite-type oxide.
