Sentences with phrase «shape memory polymers»

A recent US Patent and Trademark Office filing by Motorola proposes a rather ingenious solution to the display shattering problem: instead of glass or PET plastics, the upper layer of the display assembly will be made with shape memory polymers.

The researchers used smart shape memory polymers (SMPs) with the ability to remember one shape and change to another programmed shape when uniform heat is applied.

Their development of the new 3 - D printed objects follows earlier work the team had done using smart shape memory polymers (SMPs), which have the ability to remember one shape and change to another programmed shape when uniform heat is applied, to make objects that could fold themselves along hinges.

The team, which included researchers from the Singapore University of Technology and Design (SUTD) and Xi'an Jiaotong University in China, created the objects by printing layers of shape memory polymers with each layer designed to respond differently when exposed to heat.

It can handle a multitude of stiff and elastic materials including hydrogels, silver nanoparticle - based conductive inks, liquid crystal elastomers and shape memory polymers, or SMPs.

The first generation of shape memory polymers folded into a single predetermined shape whenever they were heated.

The company is envisioning a device that uses a «shape memory polymer» instead of glass, which may be able to reshape itself and return to the original composition by applying heat to a scratched area.

Motorola has a plan to make a self - repairing smartphone covered with shape memory polymer material.

Not exact matches

Certain plastics known as shape - memory polymers switch to predetermined shapes when triggered by heat or light.

They printed strips of a shape - memory polymer paired with a rubbery polymer called an elastomer.

When heated to 45 °C, the shape - memory polymer relaxes and allows the elastomer to bend into a new configuration.

The research creates self - folding structures from 3 - D printed patterns containing varying amounts of different smart shape - memory polymers.

The team used companion finite element simulations to predict the responses of the 3 - D printed components, which were made from varying ratios of two different commercially - available shape - memory polymers.

Using a commercially available thermally activated shape - memory polymer substrate, this 3D texturing, or «crumpling,» allows for increased surface area and opens the doors to expanded capabilities for electronics and biomaterials.

Lookman and his colleagues focused on nickel - titanium - based shape - memory alloys, but the strategy can be used for any materials class (polymers, ceramics or nanomaterials) or target properties (e.g., dielectric response, piezoelectric coefficients and band gaps).

«Our method not only enables 4 - D printing at the micron - scale, but also suggests recipes to print shape - memory polymers that can be stretched 10 times larger than those printed by commercial 3 - D printers,» said Qi «Kevin» Ge, an assistant professor at SUTD.
