Title:
PRESSURE-SENSITIVE DEVICE AND PRESSURE-SENSITIVE COMPONENT USED THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/051884
Kind Code:
A1
Abstract:
Provided is a pressure-sensitive component used for a pressure-sensitive device, which is capable of detecting both a pressing position and a pressing force, even with a simple structure. The pressure-sensitive component includes a pressure-sensitive portion (2) having: a dielectric layer (10) having a first surface (101) and a second surface (102) on the opposite side of the first surface (101); a first electrode (11) disposed on the first surface (101) side of the dielectric layer (10); and a second electrode (12) disposed on the second surface (102) side of the dielectric layer (10). The pressure-sensitive component includes at least one first terminal (21) connected to at least one location on the first electrode (11) and at least one second terminal (22) connected to at least one location on the second electrode (12). The first electrode (11) has a predetermined volume resistivity. The pressure-sensitive portion (2) deforms depending on the magnitude of a pressing force applied from the outside. Electrostatic capacitance between the first electrode (11) and the second electrode (12) changes as a result of the deformation.
