Background
The development of human beings to the present day, science and technology has made a great breakthrough in various industries, and great contribution has been made to the benefit of human beings; however, human knowledge of the human body has many dead areas, such as mechanical research of the human body is basically in the primary knowledge stage.
The method is more accurate in understanding the mechanical conditions of the human body, and is helpful for researching the diseases such as human bone deformation, cerebral palsy, hemiplegia, paralysis and the like; meanwhile, more perfect theoretical data can be provided for industry products such as intelligent correction brackets, intelligent wheelchairs, human body recovery and the like.
The sensors currently used for human body pressure research are mainly as follows: capacitive, piezoresistive, strain and in recent years new sensors have good effect on vertical pressure, sitting and lying when used on the body, but they ignore several problems:
1. The surface of the human body is an irregular curved surface, and the irregular surface changes at the moment, while the traditional sensor can only test a fixed and definite surface;
2. For some human bodies needing long-time measurement, the surface of the human body is easy to be injured due to the action of pressure, and a certain difficulty is caused for research;
3. The stress conditions of the body surface are complex, and these sensors cannot accurately measure the stress conditions of these surfaces, for example, the mechanical direction is a common disadvantage of these sensors.
Disclosure of Invention
The invention aims to provide an irregular curved surface pressure test structure which is self-adaptive to various states of a human body, can automatically adapt to the change of the curved surface of the human body, accurately test the pressure condition of the surface of the human body and simultaneously protect the surface safety of the human body in the test process.
The invention is realized by the following technical scheme:
