Bio-inspired, Moisture-Powered Hybrid Carbon Nanotube Yarn Muscles.

Scientific reports Mar 14, 2016
Hygromorph artificial muscles are attractive as self-powered actuators driven by moisture from the ambient environment. Previously reported hygromorph muscles have been largely limited to bending or torsional motions or as tensile actuators with low ...

Bi-directional series-parallel elastic actuator and overlap of the actuation layers.

Bioinspiration & biomimetics Jan 27, 2016
Several robotics applications require high torque-to-weight ratio and energy efficient actuators. Progress in that direction was made by introducing compliant elements into the actuation. A large variety of actuators were developed such as series ela...

The effect of cinnamon extract on isolated rat uterine strips.

Reproductive biology Dec 17, 2015
Cinnamon is a spice used by some populations as a traditional remedy to control blood pressure and thus hypertension. Cinnamon extract decreases contractility in some smooth muscles, but its effect on uterine smooth muscle is unknown. The aim of this...

A locust-inspired miniature jumping robot.

Bioinspiration & biomimetics Nov 25, 2015
Unmanned ground vehicles are mostly wheeled, tracked, or legged. These locomotion mechanisms have a limited ability to traverse rough terrain and obstacles that are higher than the robot's center of mass. In order to improve the mobility of small rob...

Shoulder complex linkage mechanism for humanlike musculoskeletal robot arms.

Bioinspiration & biomimetics Nov 5, 2015
The shoulder complex in the human body consists of the scapula, clavicle, humerus, and thorax and bears the load imposed by arm movements while at the same time realizing a wide range of motions. To mimic and exploit its role, several musculoskeletal...

Incidence of nonresponse and individual patterns of response following sprint interval training.

Applied physiology, nutrition, and metabolism = Physiologie appliquee, nutrition et metabolisme Nov 3, 2015
The current study sought to explore the incidence of nonresponders for maximal or submaximal performance following a variety of sprint interval training (SIT) protocols. Data from 63 young adults from 5 previously published studies were utilized in t...

Extracting motor synergies from random movements for low-dimensional task-space control of musculoskeletal robots.

Bioinspiration & biomimetics Oct 8, 2015
In the field of human motor control, the motor synergy hypothesis explains how humans simplify body control dimensionality by coordinating groups of muscles, called motor synergies, instead of controlling muscles independently. In most applications o...

Effect of bladder wall thickness on miniature pneumatic artificial muscle performance.

Bioinspiration & biomimetics Sep 28, 2015
Pneumatic artificial muscles (PAMs) are actuators known for their high power to weight ratio, natural compliance and light weight. Due to these advantages, PAMs have been used for orthotic devices and robotic limbs. Small scale PAMs have the same adv...

Anthropomorphic finger antagonistically actuated by SMA plates.

Bioinspiration & biomimetics Aug 20, 2015
Most robotic applications that contain shape memory alloy (SMA) actuators use the SMA in a linear or spring shape. In contrast, a novel robotic finger was designed in this paper using SMA plates that were thermomechanically trained to take the shape ...
