POLYMER COMPOSITE PIEZOELECTRIC MATERIAL AND A PIEZOELECTRIC DEVICE USING THE SAME CAPABLE OF PROVIDING THE POLYMER COMPOSITE PIEZOELECTRIC MATERIAL WITH A HIGH PIEZOELECTRIC PROPERTY

摘要

PURPOSE: A polymer composite piezoelectric material and a piezoelectric device using the same are provided to improve a thermal stability at a room temperature by using a piezoelectric element made of perovskite type oxide.;CONSTITUTION: A polymer composite piezoelectric element(1a) uses a piezoelectric element made of perovskite type oxide. A columnar piezoelectric element(11a) is made on an array by using a multi blade wafering saw. One columnar piezoelectric element has connectivity in a z axial direction. A polymer matrix(12a) is coated around the column. A polymer matrix is made of organic polymer resin.;COPYRIGHT KIPO 2011
