Title:
THREE-DIMENSIONAL GRIP DETECTING SENSOR
Document Type and Number:
WIPO Patent Application WO/2019/017319
Kind Code:
A1
Abstract:
The present invention has an outer wall (2) such that when a first region (A1) of the outer wall (2) is subjected to a pressing operation, the first region (A1) undergoes a first deformation in which the first region (A1) is recessed inward from the outer wall (2), and a second region (A2) different from the first region (A1) undergoes a second deformation in which the second region (A2) is projected outward from the outer wall (2). The present invention comprises: a three-dimensional object which is subjected to a pressing operation by a user; a first sensor (11) disposed on the outer wall (2) of the object; and a second sensor (12) disposed on the outer wall (2) of the object at a position asymmetric to the first sensor (11). The first sensor (11) and the second sensor (12) are each provided with: a piezoelectric film (15) which deforms in response to being subjected to a pressing operation by the user; a first electrode (31) formed on a first main surface of the piezoelectric film (15); a second electrode (32) formed on the first main surface of the piezoelectric film (15) and disposed parallel to the first electrode (31); and a reference electrode (14) formed on a second main surface of the piezoelectric film (15).
