PIEZOACTUATOR WITH LOW STRAY CAPACITANCE |
摘要 |
<p>A piezoelectric actuator includes a stack of piezoceramic layers and electrodes among the piezoceramic layers. At least one edge region of the stack does not include electrodes. A cover layer is at the at least one edge region. The cover layer has a dielectric constant that is less than a dielectric constant of a piezoceramic layer.</p> |
