Development of multi-module artificial muscle using hybrid actuator

الملخص EN

Biological muscle is considered an inspiring actuator for the researchers in the field of biorobots.

The main building unit of a muscle, sarcomere, and the study of its energy cycle is analyzed to mimic the micro-level muscle components' behavior to improve actuator performance and efficiency.

A newly developed hybrid material actuator is designed using a combination of Ionic Polymeric Metallic Composites and hydrogel to behave like the sarcomere with different deflection types.

The proposed module is arranged in two different configurations and performance is investigated for working at once or working in sequence.

A physical model is proposed, and a mathematical model of the actuator is derived and formulated using MATLAB Simulink.

The proposed arrangements show an improvement in force and displacement magnification of three times relative to the single module.

Also, working in a sequence shows promising results to work effectively to simulate muscle performance for motion profiles.
