Dynamic cardiomyoplasty using artificial muscle

Journal of Artificial Organs, 2008
Dynamic cardiomyoplasty using latissimus dorsi muscle was previously used to compensate for congestive heart failure. Now, however, this method is not acceptable because the long-term result was not as expected owing to fatigue of the skeletal muscle.

New Soft Robot Hand Configuration With Combined Biotensegrity and Thin Artificial Muscle

IEEE Robotics and Automation Letters, 2020
This letter proposes a particular tensegrity topology for a humanoid hand in which the motion of the hand is actuated using thin McKibben artificial muscles.

ARTIFICIAL MUSCLES AS ROBOTIC ACTUATORS

IFAC Proceedings Volumes, 1988
Abstract 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.

Multidirectional Artificial Muscles from Nylon

Advanced Materials, 2016
Multidirectional artificial muscles are made from highly oriented nylon filaments. Thanks to the low thermal conductivity of nylon and its anisotropic thermal expansion, bending occurs when a nylon beam is differentially heated. This heat can be generated via a Joule heating mechanism or high power laser pulses.

Artificial muscles on heat

SPIE Proceedings, 2014
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.

Nonlinear dynamics of a parametrically excited pneumatic artificial muscle (PAM) actuator with simultaneous resonance condition

Mechanism and Machine Theory, 2019
In this present work, the pneumatic artificial muscle is modelled as a single degree of freedom system and the governing nonlinear equation of motion has been derived to study the responses of the system under simultaneous simple and principal parametric
