Embodiment 1

[0024] The production process of bionic adhesive shoes is as follows

[0025] A lower limb skeletal muscle training device based on bionic adhesive materials in a microgravity environment. Bionic adhesive structure flat-press manufacturing method for through-hole nickel-based mold. Chinese invention patent. CN111993657A" discloses micro-nano imprinting technology for the preparation of adhesive materials. The preparation process can be found in figure 2 , the main steps are to place the side of the mold with the end-expanded structure on the elastic liner, and coat a uniform thermosetting silicone rubber prepolymer on the other side of the mold. The prepolymer has a tensile strength of 15Mpa and a Shore hardness of 75A, and then as for the nanoimprinting equipment, uniform pressure is applied on the upper part of the prepolymer, and the amount of depression at the end of the adhesive material is changed by adjusting the applied pressure. After the prepolymer is heated and cu...

Embodiment 2

[0030] The preparation process of the biomimetic adhesive material is as follows. The polyurethane acrylate is evenly coated on the upper side of the silicon mold that has undergone anti-adhesive treatment, and then placed in the nanoimprinting equipment. After vacuuming until the air bubbles are completely eliminated, turn on the pressure, and turn on the UV light after it is completely filled. Light source, light for one minute to complete curing, demoulding to obtain hollow hexagonal prism biomimetic adhesive material. Then, the terminal expansion structure of the adhesive material was prepared by dipping. The specific method was to spin coat a layer of urethane acrylate prepolymer with a thickness of 5um on the glass sheet with a homogenizer, and then place the side of the adhesive material with the microstructure on the Spin-coat the prepolymer on the glass, let it stand for 15 seconds, place the adhesive material on the anti-adhesive silicon wafer, let it stand for 8 hour...

Abstract

The invention discloses a bionic adhesive material-based limb bone muscle exercise device in a microgravity environment. The device consists of bionic adhesive shoes and a training flat plate, the bottom of the bionic adhesive shoe is provided with a microstructure array capable of generating adhesive force, and the training flat plate is composed of a light alloy flat plate, a silicone rubber coating layer and an adhesive material for fixing. According to the scheme, the vacuum adsorption force generated when the bionic adhesion material makes contact with the surface of the training flat plate and the collaborative adhesion force of Van der Waals force are used for simulating the gravity lacked in the space environment, the bionic adhesion device can increase the sole contact force in the exercise process in the weightless environment, and the stimulation amount of the lower limb bone muscle system is increased; bone loss and amyotrophy caused by microgravity are relieved; in addition, the device can assist the astronaut to combine exercise into daily work based on foot position fixation in the work process, the exercise is closer to ground work, and the continuous work efficiency of the astronaut in the weightless environment is improved.

Description

technical field [0001] The invention relates to the field of aerospace equipment, in particular to a device for exercising lower limb skeletal muscles in a microgravity environment based on bionic adhesive materials. Background technique [0002] The field of aerospace is one of the most influential scientific fields in the process of human understanding and transformation of nature. The level of manned spaceflight technology can not only reflect the comprehensive national strength of a country, but also is closely related to national defense and national security. With the development of aerospace technology, there are more and more space station tasks that require astronauts to perform, and the time that astronauts stay in the space station is also increasing. Studies have shown that microgravity is also likely to cause a series of physiological effects such as cardiovascular dysfunction, bone decalcification, and muscle atrophy in astronauts, which will seriously affect t...
