Provided are a piezoluminescence structure, a piezoelectric structure, a manufacturing method thereof, and a high-sensitivity pressure sensor using the same. The piezoelectric structure includes: a plurality of perovskite material layers each including a material having an ABOperovskite structure; and interlayers inserted between the plurality of perovskite material layers and including A*O which is a metal oxide having reaction resistance to CO. Here, A and A* are different elements and are one of an alkaline earth metal element, an alkali metal element, a lanthanide element, and a post-transition metal element, B is a transition metal element, O is an oxygen element, and n is a positive (+) integer. The piezoelectric structure may be a piezoluminescence structure.

Piezoluminescence structure, piezoelectric structure, manufacturing method thereof, and high sensitivity pressure sensor using the same

The present invention relates to a piezoelectric structure, a method of fabricating the same, and a pressure sensor using the same. A piezoelectric structure comprises perovskite structure layers including a material having an ABOperovskite structure and an interlayer including a metal oxide A*O interposed between the perovskite structure layers. A or A*is one of an alkaline earth metal element, an alkali metal element, a lanthanum group element, and a post-transition metal element, B is a transition metal element, and O is an oxygen element.
