Abstract An emerging technology for producing programmable stimuli‐response materials, 4D printing, is currently confined to shape changing. A new type of printing that produces shape–color double‐responsive materials similar those ubiquitous in biomaterials systems, such as octopuses simultaneously altering their skin color and response environmental stimuli, presented. Shape–color composites are prepared through the incorporation shape‐memory polymer (polylactic acid) thermochromic...
Abstract Environmentally fueled sustainable autonomous locomotion is an advanced intelligent behavior analogous to unconscious actions in biological organisms, such as heartbeat and peristalsis. In this study, a self‐sustaining oscillating soft robot introduced with eccentric hinge structures inspired by the crawling of mollusks. A parameter‐encoded 4D printing method utilized pre‐program local strain structure, thus endows motions under constant thermal field. Through coupling design...
Abstract Multistage shape changing is essential for soft robots and actuators, which difficult to achieve via current 4D printing methods. While smart materials structures are widely investigated, the effect of 3D parameters on behaviors, other hand, not adequately explored thus far. Here, it proposed program multistage memory variable recovery force by designing parameters. Specifically, effects nozzle temperature, layer thickness, geometric filling angle properties polylactic acid...
The aim of this paper was to provide a better understanding the mechanical behaviour laminated-bamboo lumber nailed connection loaded monotonically. specimens varied in nail diameter, edge distance and loading angle grain. For less than six times diameter (6d), failed prematurely at lower load exhibited moderate ductility behaviour. Two plastic hinges formed inside side core members, with crushing laminated bamboo fibres, if minimum construction requirements were satisfied. It is found that...
The electrical breakdown is a bottleneck preventing AgNW networks from being used in high-current electronics such as transparent heaters or similar applications. process of failure confirms that Joule-heating plays key role the formation cracks perpendicular to voltage direction. To improve transfer Joule heating, solution-processed ZnO nanoparticles were deposited on gravure printed random network with good transparency. AgNW-ZnO nanocomposites show better heating uniformity at higher...
Abstract Morphing botanical tissues and animal muscles are all fiber-mediated composites, in which fibers play a passive active role, respectively. Herein, inspired by the mechanism of functioning morphing muscles, we propose two sorts fiber-dominated composite actuators. First, deformation awned seeds response to humidity change, fabricate actuators using non-active aligned carbon via 4D printing method. The effects process parameters, structural fiber angles on printed examined....
In the field of roads, due to effect vehicle loads, piezoelectric materials under road surface can convert mechanical vibration into electrical energy, which be further used in facilities such as traffic signals and street lamps. The barium titanate/polyvinylidene fluoride (BaTiO3/PVDF) composite, most common hybrid ceramic-polymer system, was widely various fields because composite combines good dielectric property ceramic with flexibility PVDF material. Previous studies have found that...
The pressure matching performance of the constant area supersonic-supersonic ejector has been studied by varying primary and secondary Mach numbers.The effect fluid injection configurations in ejector, namely peripheral central, investigated as well.Schlieren pictures flow structure former part mixing duct with different stagnation ratio flows have taken.Pressure ratios at limiting condition obtained from results optical measurements.Additionally, a computational dynamics analysis performed...
In view of the problems low stiffness, small driving force and large balloon effect existing in current soft actuator, this paper proposes an optimization method to enhance overall stiffness gripper by using rigid components based on multi-cavity pneumatic actuator.
