RHOMBOHEDRAL-PHASE BARIUM TITANATE AS A PIEZOELECTRIC TRANSDUCER |
| 摘要 |
A piezoelectric transducer includes a barium-titanate-based piezoelectric material having a poled, rhombohedral structure. The rhombohedral barium titanate structure can include a dopant, such as KNbO3, BaHfO3, BaSnO3, BaZrO3 or KTaO3. The piezoelectric transducer can be used either as an actuator or as a sensor.
