Document Type and Number:
WIPO Patent Application WO/2021/143271
Kind Code:
A1
Abstract:
Provided are a sensor (301), a device, a sensing method and apparatus, and a computer-readable storage medium. The sensor (301) comprises: an upper electrode layer (301-1), a dielectric layer (301-2) and a lower electrode layer (301-3), wherein a first dielectric layer face (301-21) of the dielectric layer (301-2) is attached to a first upper electrode face (301-11) of the upper electrode layer (301-1); a second dielectric layer face (301-22) of the dielectric layer (301-2) is attached to a first lower electrode face (301-31) of the lower electrode layer (301-3); the second dielectric layer face (301-22) is opposite the first dielectric layer face (301-21); the upper electrode layer (301-1) comprises at least two sub-upper electrodes (301-12) arranged in an array; and there is an electrode gap (301-121) between the at least two sub-upper electrodes (301-12), information of the distance to an approaching object (800) is determined according to first capacitance information at the electrode gap (301-121), and under the action of the dielectric layer (301-2), an acting force which acts on a contact object (700) is determined according to second capacitance information between the upper electrode layer (301-1) and the lower electrode layer (301-3). The diversity of the sensing functions of the sensor (301) can be improved.
