▎ 摘　　要

NOVELTY - The piezoelectric element (100) has an elastic non-conductor element (120) that is arranged at upper side of a plate-shaped graphene layer (110). Another plate-shaped graphene layer (130) is arranged on upper side of the non-conductor element. The conductor elements are respectively connected to plate-shaped graphene layer. USE - Piezoelectric element. ADVANTAGE - The thin film type piezoelectric element is formed using graphene layers such that the electrical output can be increased. The damage of the piezoelectric element can be prevented. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the piezoelectric element.
