Abstract
The invention belongs to the technical field of distributed pressure and displacement measurement, and discloses a distributed flexible force position measurement device based on the Hall effect. The measurement device includes a protective layer, a plurality of flexible Hall force position sensors, and a layer and a bottom layer, the middle layer is arranged on the bottom layer; a plurality of the flexible Hall force position sensors are arranged on the middle layer at intervals; the protective layer is arranged on the middle layer , which covers the flexible Hall force level sensor; the flexible Hall force level sensor senses the received pressure through deformation, and generates a corresponding voltage signal when it is subjected to pressure; the measuring device also includes a sensor connected to the The processing module of the flexible Hall force level sensor, the processing module is used to collect the voltage signal generated by the flexible Hall force level sensor, and calculate and obtain the pressure value and the displacement value according to the voltage signal. The invention improves the efficiency and completes the work.
Description
technical field [0001] The invention belongs to the related technical field of distributed pressure and displacement measurement, and more specifically relates to a distributed flexible force position measurement device based on the Hall effect. Background technique [0002] In the fields of rehabilitation medicine and industrial measurement, the measurement of distributed pressure and contact surface shape is often involved. For example, in foot medicine, quantitative analysis of the pressure part of the foot and the shape detection of the sole of the foot can assist doctors in various medical diagnoses, Surgical evaluation, gait evaluation of special populations, sports medicine scientific research evaluation, etc., can also help shoe factories design insoles and so on. [0003] At present, there are few devices that measure distributed force and displacement at the same time, and generally measure force or displacement separately. Common sensors for measuring force alone...
