Title:
CAPACITIVE SENSOR AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/113862
Kind Code:
A1
Abstract:
Disclosed in the present utility model are a capacitive sensor and an electronic device. The capacitive sensor comprises a substrate, a plurality of first sensing electrodes, and a plurality of second sensing electrodes. The plurality of first sensing electrodes are formed on the substrate and used for fingerprints capacitively coupled to a target object. The plurality of second sensing electrodes are formed on the substrate and used for sweat holes capacitively coupled to the target object, the size of the plurality of second sensing electrodes being smaller than that of the plurality of first sensing electrodes. The electronic device includes the capacitive sensor.
