A Liquid Metal Artificial Muscle
Advanced Materials, 2021AbstractArtificial muscles possess a vast potential in accelerating the development of robotics, exoskeletons, and prosthetics. Although a variety of emerging actuator technologies are reported, they suffer from several issues, such as high driving voltages, large hysteresis, and water intolerance.

Fuel-Powered Artificial Muscles
Science, 2006Artificial muscles and electric motors found in autonomous robots and prosthetic limbs are typically battery-powered, which severely restricts the duration of their performance and can necessitate long inactivity during battery recharge. To help solve these problems, we demonstrated two types of artificial muscles that convert the chemical energy of ...

Transversal Pneumatic Artificial Muscles
2015 10th International Workshop on Robot Motion and Control (RoMoCo), 2015The paper presents an innovative construction of Pneumatic Artificial Muscles. Due to transverse deformation of the muscle, it allows obtaining a linear displacement by changing a diameter of a muscle. The new type of drive, which is represented by this solution, can be used in a robot designed for exploration of a human intestine.

Axial vibration of an artificial muscle
2015 IEEE 15th International Conference on Bioinformatics and Bioengineering (BIBE), 2015Significant number of muscles can be assumed to be of longitudinal type where the length is much higher than its cross-section. Usual motion of the longitudinal muscles is axial due to its contraction and dilatation. Our aim is to investigate the axial vibration of such muscles.

ARTIFICIAL MUSCLES AS ROBOTIC ACTUATORS
IFAC Proceedings Volumes, 1988Abstract An artificial muscle is introduced which responses to chemical stimulation producing an actuator for use in robotic applications. A mathematical model of the physical and chemical processes involved has been developed and this has been incorporated into a simulation of the ‘muscular’ actions which are occuring.

Applied Physics Letters, 2015
Artificial muscles are soft actuators with the capability of either bending or contraction/elongation subjected to external stimulation. However, there are currently no artificial muscles that can accomplish these actions simultaneously. We found that the single layered, latticed microstructure of onion epidermal cells after acid treatment became ...

Many devices and processes produce low grade waste heat. Some of these include combustion engines, electrical circuits, biological processes and industrial processes. To harvest this heat energy thermoelectric devices, using the Seebeck effect, are commonly used. However, these devices have limitations in efficiency, and usable voltage.

Journal of Intelligent Material Systems and Structures, 2012
This article presents hydraulic artificial muscles as a viable alternative to pneumatic artificial muscles. Despite the actuation mechanism being similar to its pneumatic counterpart, hydraulic artificial muscles have not been widely studied. Hydraulic artificial muscles offer all the same advantages of pneumatic artificial muscles, such as compliance,
