State determination method using capacitance type detection sensor, capacitance type detection sensor module and capacitance type detection sensor

摘要

PROBLEM TO BE SOLVED: To provide a capacitance type detection sensor capable of improving the presence / absence of proximity of an object such as a human body and the detection accuracy of the pressure received from the object. SOLUTION: A pair of first electrodes 111, 112 are arranged in a state of being separated in a direction parallel to a contact surface 102 of a base material 10 made of a dielectric material and at least partially in contact with the base material 10. Has been done. At least one of the pair of second electrodes 121 and 122 is located farther from the contact surface 102 of the base material 10 than the pair of first electrodes 111 and 112 in the direction perpendicular to the contact surface 102 of the base material 10. It is arranged so as to overlap the first electrode and sandwich the base material 10. The proximity state of the object Q to the contact surface 102 of the base material 10 is detected according to the measurement result of the capacitance C1 between the pair of first electrodes 111 and 112. The pressure acting on the base material 10 is detected from the object Q in contact with the contact surface 102 of the base material 10 according to the measurement result of the capacitance C2 between the pair of second electrodes 121 and 122.
