| titleOfInvention | Piezoelectric material |
| abstract | Provided is a piezoelectric body in which an appropriate amount of an appropriate additive is added to improve a power generation amount per unit volume. In a piezoelectric element structure, 1 is a piezoelectric body manufactured by adding 1 mol% of niobium as an additive, and applying a polarization electric field of 1.5 kV / mm in the process of polarization, 2 is an electrode, 3 , 4 are output terminals. Electrodes 2 are formed on the upper and lower surfaces of the piezoelectric body 1 to constitute a piezoelectric element, and the electrodes 2 of the stacked piezoelectric elements are connected with the same polarity to form output terminals 3 and 4. As a base material of the piezoelectric body, lead zirconate titanate (PZT) which is a piezoelectric power generator is preferable. As an additive to be added to the base material in an amount of 0.1 to 4 mol%, it is introduced into the B site having a perovskite crystal structure such as niobium, tungsten, tantalum, lanthanum, antimony, bismuth, and thorium oxide, and has a low elastic modulus. An element that can supply a donor to a base material as an element is preferable. [Selection] Figure 5 |
