Document Type and Number:
WIPO Patent Application WO/2023/047776
Kind Code:
A1
Abstract:
[Problem] To provide: an input device which uses haptic technology and is excellent in operational feeling; an input system; and a method for driving the input device. [Solution] This input device comprises a housing and a piezoelectric actuator. The piezoelectric actuator comprises: a piezoelectric body layer which is mounted on the housing and composed of a piezoelectric material; a positive electrode internal electrode provided in the piezoelectric body layer; and a negative electrode internal electrode which is provided in the piezoelectric body layer and faces the positive electrode internal electrode with the piezoelectric body layer therebetween, wherein when a voltage is applied between the positive electrode internal electrode and the negative electrode internal electrode, the piezoelectric actuator is stretched or contracted in a direction perpendicular to the electrode surfaces of the positive electrode internal electrode and the negative electrode internal electrode.
