“…Skeletal muscles are complex structures that operate synergistically to produce movement, and their function has been extensively studied in engineering fields for the purpose of mimicking it. [1][2][3] Accordingly, researchers worldwide have developed artificial muscles that mimic the biological system as actuators to achieve capabilities comparable to natural muscles. [4][5][6][7] Various approaches have been taken to develop artificial muscles over the past few decades.…”

Human skeletal muscle is widely considered to be the most efficient actuator, leading to extensive research on developing artificial muscles. Bioinspired technologies such as soft robotics and biomimetics are used to produce artificial muscles with performance characteristics similar to those of their biological counterpart. Despite the complexity of human skeletal muscle, advanced engineering materials and unique approaches can help develop an artificial muscle that replicates its kinematic motions. Herein, biomimetic modular artificial muscle (BiMAM), which is the culmination of different design strategies, is presented, and fabrication methods aimed at developing this BiMAM. This chemically driven modular artificial muscle uses shape memory alloy coated with nanomaterials and nano‐catalysts. Herein, a high‐energy density fuel is employed to actuate this artificial muscle, enabling fast and efficient outputs. Multiple performance characteristics are determined by conducting controlled experiments. Various methods are demonstrated to control the fuel‐based valve system and the actuation of the chemically driven artificial muscle. Lastly, to evaluate its functionality, the curling movement of a robotic finger using BiMAM is demonstrated.
