CPC G06F 3/044 (2013.01) [G06F 3/0412 (2013.01); G06F 3/0414 (2013.01)] | 13 Claims |
1. An electronic device, comprising:
a housing comprising a wall;
a strain sensor group comprising at least one strain sensor attached on the wall, wherein each of the at least one strain sensor is configured to detect a deformation of the wall in a single direction, the deformation involves a direction and a magnitude, and the direction is a deformation-sensitive direction, wherein the at least one strain sensor comprises N strain sensors, wherein N is an integer equal to or greater than 2, the N strain sensors detect the deformation of the wall in N directions, respectively, and an angle between each two adjacent directions of the N directions is 180/N degrees; and
at least one analog-to-digital converter, which has an input terminal connected to an output terminal of the at least one strain sensor and has an output terminal connected to a controller, the at least one analog-to-digital converter is configured to convert a detection signal indicating the direction and the magnitude of the wall from the at least one strain sensor into a digital signal; and
the controller configured to trigger a first event in the electronic device based on the digital signal,
wherein the wall of the housing is electrically connected to a grounding terminal of a printed circuit board (PCB) of the electronic device by an inductor, the inductor has a first terminal connected to the wall of the housing and a second terminal connected to the grounding terminal of the PCB,
wherein the electronic device further comprises a capacitor electronically connected across the first terminal and the second terminal of the inductor.
