Title:
SENSING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/283966
Kind Code:
A1
Abstract:
A sensing apparatus (10, 210), comprising: an elastic component (20, 220, 720, 820); a sensing cavity (50, 250), wherein the elastic component (20, 220, 720, 820) forms a first sidewall of the sensing cavity (50, 250); and a transduction component (30, 230), configured to obtain a sensing signal and convert the sensing signal into an electrical signal, wherein the transduction component (30, 230) is communicated with the sensing cavity (50, 250), the sensing signal is correlated with the size change of the sensing cavity (50, 250), the side of the elastic component (20, 220, 720, 820) facing the sensing cavity (50, 250) is provided with a protruding structure (23, 223, 823), the elastic component (20, 220, 720, 820) drives, in response to an external signal, the protruding structure (23, 223, 823) to move, and the movement of the protruding structure (23, 223, 823) changes the size of the sensing cavity (50, 250).
