“…In recent decades, a large number of scholars have conducted, and are still conducting, research on imitating the form and function of skeletal muscles. Different types of actuators have been put forth and extensively studied for their potential applications as “artificial muscles” [ 2 ], including traditional actuator devices (such as electric motors [ 3 , 4 ], hydraulic actuators [ 5 , 6 , 7 , 8 ] and pneumatic actuators [ 9 , 10 , 11 , 12 ]) and smart materials (such as electroactive polymers [ 13 , 14 , 15 , 16 ], high-strength polymer fibers [ 17 ], magnetostrictive alloys [ 16 ] and shape memory alloys [ 1 , 2 , 18 , 19 , 20 ]).…”

“…Recently, electroactive polymers (EAPs) are attractive for a wide range of applications as artificial muscles for reasons such as their large active strains, no acoustic noise, and self-sensing ability. Unfortunately, the generated force of an EAP artificial muscle is small and the input voltage is too high (>1000 V) to be of practical use [ 15 , 21 , 22 ]. High-strength polymer fibers have the advantages of fast speed, large displacement, and the ability to withstand a greater load, which has a wide range of potential applications.…”

Inspired by the natural skeletal muscles, this paper presents a novel shape memory alloy-based artificial muscle matrix (AMM) with advantages of a large output force and displacement, flexibility, and compactness. According to the composition of the AMM, we propose a matrix control strategy to achieve independent control of the output force and displacement of the AMM. Based on the kinematics simulation and experiments, we obtained the output displacement and bearing capacity of the smart digital structure (SDS) and confirmed the effectiveness of the matrix control strategy to achieve force and displacement output independently and controllably. A bionic mechanical ankle actuated by AMM was proposed to demonstrate the actuating capability of the AMM. Experimental results show that the angle and force of the bionic mechanical ankle are output independently and have a significant gradient. In addition, by using a self-sensing method (resistance self-feedback) and PD control strategy, the output angle and force of the bionic mechanical ankle can be maintained for a long time without overheating of the AMM.

Soft actuators have received extensive attention in robotics and smart device applications due to their distinctive dexterity and compliance. Among them, hydraulic soft actuators play an important role in the area because they have much higher specific power and power density than other types such as pneumatic soft actuators. Nevertheless, the deformation of flexible materials in soft actuators brings about inherent hysteresis and nonlinearity, which severely hinders them from producing the desired movement in the presence of advanced control strategies. In this paper, previous research efforts made to enhance the driving capability and actuation efficiency of hydraulic soft actuators are illustrated and analyzed from the three aspects of architecture, materials, and control strategy. Meanwhile, the issues and challenges that have emerged when developing hydraulic soft actuators are discussed. Finally, the potential future development of hydraulic powered soft actuators is discussed.
