Document Type and Number:
WIPO Patent Application WO/2023/087324
Kind Code:
A1
Abstract:
A piezoelectric device, a vibration panel, and a haptic feedback device. The piezoelectric device comprises: at least three electrode layers (10, 20) stacked alternately, and a piezoelectric layer (30) located between every two adjacent electrode layers (10, 20). For all the electrode layers (10, 20), the electrode layers (10) located on the odd-numbered layers are electrically connected to each other, the electrode layers (20) located on the even-numbered layers are electrically connected to each other, and the electrode layers (10) located on the odd-numbered layers are insulated from the electrode layers (10) located on the even-numbered layers.
