HYBRID LARGE-AREA PRESSURE SENSOR INCLUDING CAPACITIVE SENSOR AND RESISTIVE SENSOR INTEGRATED WITH EACH OTHER
DRIVE
October 12, 2022
Disclosed is a hybrid large-area pressure sensor with a capacitive sensor and a resistive sensor integrated thereinto. The sensor includes a first electrode pattern, a second electrode pattern spaced apart from the first electrode pattern by a predetermined distance, a third electrode pattern spaced apart from the second electrode pattern by a predetermined distance, and a controller, wherein a part of the first electrode pattern, a predetermined unit area of the second electrode pattern, and a predetermined unit area of the third electrode pattern form a single unit sensing cell, a change in distance between the first electrode pattern and the second electrode pattern causes a change in the capacitance of the second electrode pattern, a contact between the second electrode pattern and the third electrode pattern causes a change in the resistance of the second electrode pattern, and the controller senses pressure corresponding to the unit sensing cell by using the change in the capacitance and the change in the resistance.
