  • Piezoelectric sensor and method for manufacturing the same
    Patent number: 8314536
    Abstract: An inexpensive piezoelectric sensor where noise unlikely occurs and a method for manufacturing the same are provided. A piezoelectric body (2) made of polymeric material, a first electrode-supporting portion (3) disposed at one side of the piezoelectric body (2) and supporting a signal electrode (3b) on a first insulator (3a), and a second electrode-supporting portion (4) disposed at the other side of the piezoelectric body (2) and supporting a ground electrode (4b) on a second insulator (4a) are included, and the first electrode-supporting portion (3) and the second electrode-supporting portion (4) are arranged so that the signal electrode (3b) and the ground electrode (4b) overlap each other in a layering direction.

  • PIEZOELECTRIC FILM SENSOR
    Publication number: 20100253183
    Abstract: A piezoelectric film sensor includes a substrate 1 having a signal electrode 2 and a ground electrode 3 formed on the surface thereof, the substrate being folded to cause the signal electrode 2 and the ground electrode 3 to be overlapped with each other in a plane view, a piezoelectric film 5 inserted between the signal electrode 2 and the ground electrode 3 formed on the substrate 1 and a bonding layer 6 for bonding the folded substrate 1 thereby to affix the signal electrode 2, the ground electrode 3 and the piezoelectric film 5 together.
