Title:
DEFORMATION DETECTING SENSOR
Document Type and Number:
WIPO Patent Application WO/2023/238682
Kind Code:
A1
Abstract:
This deformation detecting sensor comprises a holding portion which is connected to an operating panel for accepting a push operation performed by a user, and which holds the operating panel, and a piezoelectric film which is connected to the holding portion to detect deformation of the holding portion, wherein: the holding portion includes a first part connected to a housing, a second part connected to the operating panel, and resilient beam portions connecting the first part and the second part; the piezoelectric film is connected straddling the first part and the second part; the piezoelectric film includes a first piezoelectric film and a second piezoelectric film that are stacked on one another; and the first piezoelectric film and the second piezoelectric film are polarized to the same potential with mutually different polarities when bent in a stacking direction.
