Title:
PRESSURE-SENSITIVE TOUCH SENSOR AND PRESSURE-SENSITIVE TOUCH SENSOR MODULE
Document Type and Number:
WIPO Patent Application WO/2019/230634
Kind Code:
A1
Abstract:
Provided is a capacitive pressure-sensitive touch sensor and a pressure-sensitive touch sensor module, by which it becomes difficult to erroneously detect a touch onto an operation surface. Provided is a capacitive pressure-sensitive touch sensor (1), wherein: a first electrode (18) and a second electrode (20) are provided on a first surface (10a) of a substrate sheet (10); the substrate sheet (10) is folded between the first electrode (18) and the second electrode (20) such that the surface of the first electrode (18) and the surface of the second electrode (20) face each other; a slit (28) is formed in a folding line section (1d) at which the substrate sheet (10) is folded; an elastic layer (26) is provided between folded sections of the substrate sheet (10); the elastic layer (26) is compressed and deformed in the thickness direction by a pressure force; and the pressure on the operation surface is detected from a capacitance variation generated as the distance between the first electrode (18) and the second electrode (20) becomes shorter.
