Title:
SENSOR SHEET, CAPACITIVE SENSOR, AND METHOD FOR MANUFACTURING SENSOR SHEET
Document Type and Number:
WIPO Patent Application WO/2019/003946
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a sensor sheet, a capacitive sensor, and a method for manufacturing a sensor sheet with which it is possible to suppress changes in capacitance due to arrangement. This sensor sheet (1) comprises pairs of electrode layers (1X-4X, 1Y-4Y), constraint layers (32, 42) that regulate the surface-direction expansion and contraction of the electrode layers (1X-4X, 1Y-4Y), a plurality of detection parts (A(1,1)-A(4,4)) disposed in portions overlapped by the pairs of electrode layers (1X-4X, 1Y-4Y) when viewed from the lamination direction, and non-detection parts (G) disposed between the plurality of detection parts (A(1,1)-A(4,4)). In a no-load state, the constraint layers (32, 42) are disposed in at least some of the plurality of detection parts (A(1,1)-A(4,4)), and gaps (g) are partitioned in at least some of the non-detection parts (G).
