Title:
DYNAMIC OR QUASI-DYNAMIC FORCE DETECTION APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2019/154442
Kind Code:
A1
Abstract:
A dynamic or quasi-dynamic force detection apparatus and method, said apparatus specifically including a base plate (101), a piezoelectric sensing module (102) and a signal analysis module (103). The base plate (101) is used for producing an elastic wave signal according to a touch. The piezoelectric sensing module (102) is connected to the base plate (101), and is used for converting the elastic wave signal into a voltage signal. The signal analysis module (103) is connected to the piezoelectric sensing module (102), and is used for calculating, according to the voltage signal, a fluctuation change value of the voltage signal and calculating, according to the fluctuation change value, force information produced by the touch. The dynamic or quasi-dynamic force detection apparatus and method provide valid three-dimensional force information, are simple in structure, have wide applicability, and may be used in fields such as virtual keyboards, automobile electronics, smart homes, robots and aerospace.
