Acoustic sensor |
| abstract |
Disclosed are devices, systems, and methods for capturing acoustic data in an efficient manner. Some embodiments have piezoelectric sensing portions with polarization axes and conducting layers. In some embodiments, piezoelectric sensing portions can be positioned generally coplanar to each other and in partial electrical contact. In some embodiments, polarization axes of two piezoelectric sensing portions have a non-zero angle between them. Certain embodiments comprise a noise reducing element. In some embodiments, an electrode is included to detect electrical signals. |
