Title:
CAPACITANCE-TYPE PRESSURE SENSOR
Document Type and Number:
WIPO Patent Application WO/2019/098014
Kind Code:
A1
Abstract:
Peeling apart of a flexible substrate and a hard substrate is suppressed. A capacitance-type pressure sensor provided with: a flexible substrate including a first electrode, the flexible substrate being flexible; a hard substrate including a second electrode disposed facing the first electrode, the hard substrate being disposed facing the flexible substrate across a hollow part between the flexible substrate and the hard substrate; a joining part between the flexible substrate and the hard substrate, the joining part being provided so as to surround the hollow part and joining the flexible substrate and the hard substrate; and a reinforcing resin provided between the flexible substrate and the hard substrate and in the vicinity of the joining part; the capacitance-type pressure sensor being such that, in the hollow part, pressure applied toward a surface of the first electrode facing the second electrode is measured by detecting a change in capacitance produced due to flexing of the first electrode relative to the second electrode, and the reinforcing resin covers part of the flexible substrate, part of the hard substrate, and part of the joining part.
