Title:
PIEZOELECTRIC DRIVING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2022/130911
Kind Code:
A1
Abstract:
In a piezoelectric driving element (1), one fixed end (E1) is fixed to a support (40) and another free end (E2) is a driven cantilever-type piezoelectric driving element. The piezoelectric driving element (1) is provided with first piezoelectric bodies (10a, 10b) arranged on the fixed end (E1) side, and second piezoelectric bodies (20a, 20b) arranged more toward the free end (E2) side than the fixed end (E1) side. The thickness of the second piezoelectric bodies (20a, 20b) is set to be smaller than the thickness of the first piezoelectric bodies (10a, 10b).
