Title:
APPARATUS AND METHOD FOR FORCE SENSING, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/170459
Kind Code:
A1
Abstract:
An apparatus (20) and a method for force sensing, and an electronic device (1). The apparatus (20) includes a sensor (21) and a filter (22). The sensor (21) is configured to generate a first signal (V out1) which is determined based on deformation of at least a part (210) of the sensor (21) and temperature of at least the part (210) of the sensor (21). The part (210) of the sensor (21) is attached to a deformable portion (11) of the electronic device (1). The filter (22) is configured to receive the first signal (V out1), and remove a change from the first signal (V out1) to acquire a second signal (V out2), where the change is due to the temperature of the part (210) of the sensor (21). In comparison with the first signal (V out1), the second signal (V out2) is less sensitive to the temperature, and therefore can indicate the deformation of the deformable portion (11) more accurately. The electronic device (1) can make an accurate response when the deformable portion (11) deforms.
