| 摘要 |
A piezoelectric transducer (10) includes (a) a first gas matrix piezoelectric composite (12) having a side including at least one positive pole (+) and another side including at least one negative pole (−); (b) a second gas matrix piezoelectric composite (14) having a side including at least one positive pole (+) and another side including at least one negative pole (−); and (c) a substrate (28) having a first side (22) and a second side (24), wherein the substrate is positioned between the first gas matrix piezoelectric composite and the second gas matrix piezoelectric composite. Either the first or second gas matrix piezoelectric composite may include a plurality of piezoelectric rods (15), wherein each piezoelectric rod includes at least one positive pole (16) end and at least one negative pole end (18).
