Title:
CAPACITANCE DETECTION SENSOR, CAPACITANCE DETECTION SENSOR MODULE AND STATE DETERMINATION METHOD USING CAPACITANCE DETECTION SENSOR
Document Type and Number:
WIPO Patent Application WO/2021/065177
Kind Code:
A1
Abstract:
Provided is a capacitance detection sensor capable of improving the accuracy of detecting whether or not an object such as a person is approaching and detecting the pressure received from said object. A pair of first electrodes 111, 112 are separated from one another in a direction parallel to a contact surface 102 of a substrate 10 comprising a dielectric body, and are positioned so as to at least partially contact the substrate 10. A pair of second electrodes 121, 122 sandwich the substrate 10 and overlap at least one of the first electrodes in a direction perpendicular to the contact surface 102 of the substrate 10 from a location which is farther from the contact surface 102 of the substrate 10 than is the pair of first electrodes 111, 112. The state of the approach of an object Q toward the contact surface 102 of the substrate 10 is detected according to the measurement results of the capacitance C1 between the pair of first electrodes 111, 112. The pressure acting on the substrate 10 from the object Q contacting the contact surface 102 of the substrate 10 is detected according to the measurement results of the capacitance C2 between the pair of second electrodes 121, 122.
