Shape-Morphing Nanocomposite Origami

چکیده
Nature provides a vast array of solid materials that repeatedly and reversibly transform in shape in response to environmental variations. This property is essential, for example, for new energy-saving technologies, efficient collection of solar radiation, and thermal management. Here we report a similar shape-morphing mechanism using differential swelling of hydrophilic polyelectrolyte multilayer inkjets deposited on an LBL carbon nanotube (CNT) composite. The out-of-plane deflection can be precisely controlled, as predicted by theoretical analysis. We also demonstrate a controlled and stimuli-responsive twisting motion on a spiral-shaped LBL nanocomposite. By mimicking the motions achieved in nature, this method offers new opportunities for the design and fabrication of functional stimuli-responsive shape-morphing nanoscale and microscale structures for a variety of applications.

Robotic origamis: self-morphing modular robots
Programmable matter is a material that produces distinctive shapes or patterns according to a given command. Often they are composed of interconnected modular elements that are able to make or break the connections or alter relative orientation. We present programmable matter based on robotic origami that demonstrates the capability to fold into 3D shapes starting from a nominally 2D sheet. Thi...

The area of smart materials is a hot topic as it allows access to adaptive/responsive materials with selfhealing, shape memory, or actuation behavior. Indeed, scientists can make all manner of materials on-scale with controllable and remarkable properties, but designing materials with mechanical adaptability is much more challenging. Although the sea cucumber might seem like an unlikely source ...

Harmonious developments of electrical and mechanical performances are crucial for stretchable sensors in structural health monitoring (SHM) of flexible aircraft such as aerostats and morphing aircrafts. In this study, we prepared a highly durable ternary conductive nanocomposite made of polydimethylsiloxane (PDMS), carbon black (CB) and multi-walled carbon nanotubes (MWCNTs) to fabricate stretc...
متن کاملObject Shape Morphing with Intermediate Reflectance Properties
Image morphing techniques can create a smooth transition between two images. However, one of the main weakness of the image morphing technique is that intermediate images in the transition often have physically incorrect shading such as highlights and shadows. Moreover, we cannot alter viewing and lighting conditions when creating the intermediate images. That is because those images are obtain...
متن کاملFlight Dynamics and Control of a Vertical Tailless Aircraft
In the field of aeronautics, shape morphing has been used to identify those aircraft that undergo substantial geometrical changes in their external shape to enhance or adapt to their mission profiles during flight. This creates superior system capabilities not possible without morphing shape changes. The objective of morphing concepts is to develop high performance aircraft with lifting surface...
