Abstract

Background

With the development of automation technology, various actuators are widely used in fields such as robotics and biomedical equipment. However, traditional mechanical actuators have some problems, such as poor movement flexibility and insufficient movement flexibility, because of the characteristics of the mechanical structure. As a new driving mode, artificial muscle actuators can provide enough power and speed while remaining light and flexible, making them highly adaptable in various applications. As a result, artificial muscle actuators are gaining increasing attention.

Objective

The purpose of this study is to give an overview of the patents related to artificial muscle actuators and introduce their principles, classifications, latest progress, and future development.

Methods

This patent paper reviews the current representative patents related to artificial muscle actuators, such as fluid pressure artificial muscle actuators, thermal deformation artificial muscle actuators, and electrical deformation artificial muscle actuators.

Results

By investigating various patents of artificial muscle actuators, the main problems of artificial muscle actuators are summarized and analyzed, such as low energy efficiency and lack of self-learning ability. In addition, the development trend of artificial muscle actuators is also discussed.

Conclusion

The optimization of artificial muscle actuators is beneficial to make the output of artificial mechanical devices more stable and more convenient for human-machine combinations. More related patents will be invented in the future.
