Description

Technical Field

[0001] The invention belongs to the technical field of artificial muscle performance testing, and in particular relates to an artificial muscle material performance testing device. Background Art

[0002] IPMC (ion exchange membrane metal composite) is an ionic polymer-metal composite (EAP) with actuation properties very similar to biological muscle, hence its name "artificial muscle." IPMC is a relatively soft and elastic material that can produce large deformations with a relatively low driving voltage. It can operate in humid environments, has excellent biocompatibility, and can be formed into thin strips. It is a suitable material for the development of biomimetic robots, and experimental testing of it is of great significance to the development of biomimetic robots and even artificial intelligence. However, its development and application are primarily limited by two limitations: low output force and dependence on aqueous or humid environments. In recent years, extensive research has focused on these two areas to further improve IPMC's performance and potential for industrial application.

[0003] Force output and deformation displacement are two important indicators for measuring IPMC performance. Currently, the force and displacement testing systems for IPMC are piecemeal and not an organic whole. Moreover, they cannot meet the performance requirements of both out-of-water and in-water environments. Most of them can only be tested in out-of-water and in-water environments respectively through two sets of experimental equipment, which is very inconvenient to operate.

[0004] During the actual use of existing experimental platforms for IPMC artificial muscle material performance testing, the positions of force sensors and displacement sensors are usually fixed during testing, or can only be adjusted with a single degree of freedom. It is often impossible to change the position according to the position change of the material to meet the measurement requirements. After the test material is fixed, the angle is single, resulting in a small test range. Manual adjustment is required, which is more labor-intensive, resulting in reduced test efficiency and reduced test accuracy.

[0005] Therefore, there is an urgent need for an integrated device that can not only test the mechanical properties and displacement output of IPMC, but also meet the requirements of atmospheric and water environment testing, and can meet the multi-degree-of-freedom adjustment of the test material, and can adjust the sensor position as the test material is adjusted.
