Rheological properties of a polysaccharide from floral mushrooms cultivated in Huangshan Mountain.
Carbohydrate polymers
Dec 12, 2015
A polysaccharide fraction (FMPS) was isolated from floral mushrooms cultivated in Huangshan Mountain, and the rheological properties of FMPS in aqueous solutions were investigated. The FMPS solution showed shear-thinning behavior at 25°C. Dynamic vis...
Analytical model and stability analysis of the leading edge spar of a passively morphing ornithopter wing.
Bioinspiration & biomimetics
Oct 26, 2015
This paper presents the stability analysis of the leading edge spar of a flapping wing unmanned air vehicle with a compliant spine inserted in it. The compliant spine is a mechanism that was designed to be flexible during the upstroke and stiff durin...
Distributed flow sensing for closed-loop speed control of a flexible fish robot.
Bioinspiration & biomimetics
Oct 23, 2015
Flexibility plays an important role in fish behavior by enabling high maneuverability for predator avoidance and swimming in turbulent flow. This paper presents a novel flexible fish robot equipped with distributed pressure sensors for flow sensing. ...
The effect of aspect ratio on the leading-edge vortex over an insect-like flapping wing.
Bioinspiration & biomimetics
Oct 9, 2015
Insect wing shapes are diverse and a renowned source of inspiration for the new generation of autonomous flapping vehicles, yet the aerodynamic consequences of varying geometry is not well understood. One of the most defining and aerodynamically sign...
Principles of appendage design in robots and animals determining terradynamic performance on flowable ground.
Bioinspiration & biomimetics
Oct 8, 2015
Natural substrates like sand, soil, leaf litter and snow vary widely in penetration resistance. To search for principles of appendage design in robots and animals that permit high performance on such flowable ground, we developed a ground control tec...
Effects of non-uniform stiffness on the swimming performance of a passively-flexing, fish-like foil model.
Bioinspiration & biomimetics
Oct 8, 2015
Simple mechanical models emulating fish have been used recently to enable targeted study of individual factors contributing to swimming locomotion without the confounding complexity of the whole fish body. Yet, unlike these uniform models, the fish b...
A biomimetic underwater vehicle actuated by waves with ionic polymer-metal composite soft sensors.
Bioinspiration & biomimetics
Sep 28, 2015
The ionic polymer-metal composite (IPMC) is a soft material based actuator and sensor and has a promising potential in underwater application. This paper describes a hybrid biomimetic underwater vehicle that uses IPMCs as sensors. Propelled by the en...
Modelling cephalopod-inspired pulsed-jet locomotion for underwater soft robots.
Bioinspiration & biomimetics
Sep 28, 2015
Cephalopods (i.e., octopuses and squids) are being looked upon as a source of inspiration for the development of unmanned underwater vehicles. One kind of cephalopod-inspired soft-bodied vehicle developed by the authors entails a hollow, elastic shel...
Bifunctional composite from spent "Cyprus coffee" for tetracycline removal and phenol degradation: Solar-Fenton process and artificial neural network.
International journal of biological macromolecules
Aug 28, 2015
Removals of tetracycline and photocatalytic degradation of phenol by Fe3O4/coffee residue (MCC) were investigated. Brunauer-Emmett-Teller (BET), vibrating sample magnetometer (VSM) and Boehm titration were employed to characterize MCC. Artificial neu...
Tactile soft-sparse mean fluid-flow imaging with a robotic whisker array.
Bioinspiration & biomimetics
Aug 4, 2015
An array of whiskers is critical to many mammals to survive in their environment. However, current engineered systems generally employ vision, radar or sonar to explore the surroundings, not having sufficiently benefited from tactile perception. Insp...
