Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] According to one or more embodiments, a method for reliability evaluation of smart clothing flexible pressure sensor wearing test data is disclosed, such as figure 1 shown, including the following steps:

[0031] S1. Scan the required parts of the human body through CT, establish the contour model of human skeleton and soft tissue through reverse engineering, establish the clothing model in finite element software, and assemble the clothing model with the contour model of human skeleton and soft tissue;

[0032] S2. Set the parameters of the established model, the bone is set as an isotropic linear elastic body, the soft tissue is set as a linear viscoelastic body, and the clothing is set as a linear elastic body;

[0033] S3. Setting the local coordinate system to determine the rotation position and direction of the bone joint;

[0034] S4. Perform ...

Abstract

The invention discloses a deliability evaluation method for dressing test data of a flexible pressure sensor of intelligent clothing, and solves the defects that the existing pressure simulation is difficult to approach real human body data, and the test reliability is poor. According to the technical scheme, local parts of a human body are scanned through CT, human skeleton and soft tissue models are established through reverse engineering, a human garment model is established through finite element modeling and assembled with the human body model, skeletons are arranged to be isotropic linear elastomers, soft tissues are arranged to be linear viscoelastic materials, and garments are arranged to be linear elastomers. According to the reliability evaluation method for the dressing test data of the intelligent clothing flexible pressure sensor, the distribution simulation of the clothing pressure under the dynamic condition is carried out, and the reliability evaluation under the motion state can be conveniently and reliably carried out.

Description

technical field [0001] The invention relates to an evaluation method, in particular to a reliability evaluation method for wearing test data of a flexible pressure sensor of smart clothing. Background technique [0002] With the development and progress of science and technology, smart clothing has gradually entered people's field of vision. Smart clothing usually embeds smart fibers or electronic devices on the surface of clothing to realize real-time monitoring and collection of human physiological signal data. Since the human body is in motion most of the time, the collision and friction deformation between the clothing and the human body, the physiological and psychological changes of the human body, and the wearing environment and wearing times of the smart clothing may all affect the data collection. affect the stability and reliability of the system. [0003] At present, the relevant research on the dynamic contact pressure between clothing and human body is still i...
