Ratchet-integrated pneumatic actuator (RIPA): a large-stroke soft linear actuator inspired by sarcomere muscle contraction.
Bioinspiration & biomimetics
Mar 25, 2020
Pneumatic artificial muscles (PAMs) have a wide range of robotics applications, especially in soft robots, for their ability to generate linear force and displacement with the soft, lightweight, compact, and safe characteristics as well as high power...
Novel Bending and Helical Extensile/Contractile Pneumatic Artificial Muscles Inspired by Elephant Trunk.
Soft robotics
Mar 4, 2020
Pneumatic artificial muscles (PAMs) are an extensively investigated type of soft actuator. However, the PAM motions have been limited somewhat to uniaxial contraction and extension, restraining the development of PAMs. Given the current strong intere...
Recurrent Braiding of Thin McKibben Muscles to Overcome Their Limitation of Contraction.
Soft robotics
Nov 7, 2019
This study presents a novel idea of rebraiding thin McKibben muscles to overcome their limitation of contraction. The thin McKibben muscles, presented in the authors' previous work, have the flexibility that allows them to be braided. According to th...
Neuromuscular actuation of biohybrid motile bots.
Proceedings of the National Academy of Sciences of the United States of America
Sep 16, 2019
The integration of muscle cells with soft robotics in recent years has led to the development of biohybrid machines capable of untethered locomotion. A major frontier that currently remains unexplored is neuronal actuation and control of such muscle-...
Design and Feasibility Study of a Leg-exoskeleton Assistive Wheelchair Robot with Tests on Gluteus Medius Muscles.
Sensors (Basel, Switzerland)
Jan 28, 2019
The muscles of the lower limbs directly influence leg motion, therefore, lower limb muscle exercise is important for persons living with lower limb disabilities. This paper presents a medical assistive robot with leg exoskeletons for locomotion and l...
Realizing the potential of dielectric elastomer artificial muscles.
Proceedings of the National Academy of Sciences of the United States of America
Jan 24, 2019
Soft robotics represents a new set of technologies aimed at operating in natural environments and near the human body. To interact with their environment, soft robots require artificial muscles to actuate movement. These artificial muscles need to be...
Influence of Nanosilver on Endothelial Function and Vascular Reactivity of Isolated Rabbit Carotid Artery.
Nigerian journal of physiological sciences : official publication of the Physiological Society of Nigeria
Dec 30, 2018
There is paucity of information on the effects and mechanism of action of Nanosilver on vascular tone andendothelial function in spite of the upsurge in nanotechnology application in biomedicine. The present study determined theeffect of Nanosilver o...
Origami-Based Vacuum Pneumatic Artificial Muscles with Large Contraction Ratios.
Soft robotics
Oct 19, 2018
A novel linear actuator called origami-based vacuum pneumatic artificial muscle (OV-PAM) is proposed in this study that can produce large forces (>400 N) with a contraction ratio >90% of the active length of the actuator. Moreover, some of the design...
Regulation of C2C12 Differentiation and Control of the Beating Dynamics of Contractile Cells for a Muscle-Driven Biosyncretic Crawler by Electrical Stimulation.
Soft robotics
Oct 18, 2018
Biosyncretic robots have potential advantages associated with both living organisms and electromechanical systems. Skeletal muscle tissue is a candidate as bioactuators for biosyncretic robots because of its excellent contraction force and controllab...
The Design and Mathematical Model of a Novel Variable Stiffness Extensor-Contractor Pneumatic Artificial Muscle.
Soft robotics
Jul 24, 2018
This article presents the design of a novel extensor-contractor pneumatic artificial muscle (ECPAM). This new actuator has numerous advantages over traditional pneumatic artificial muscles. These include the abilities to both contract and extend rela...
