3D Printing of Flexible Circuits

A process was developed for 3D printing that can be used to produce transparent and mechanically flexible electronic circuits. The electronics consist of a mesh of silver nanowires that can be printed in suspension and embedded in various flexible and transparent plastics (polymers). This technology can enable...

Shear Assisted Processing and Extrusion (ShAPE™) allows creation of wire, bar, and tubular extrusions that show significant improvement in material properties; for example, magnesium extrusions have...

INSIDER: Nanotechnology

Wearable devices that harvest energy from movement are not a new idea, but a material created at Rice University may make them more practical.

INSIDER: Electronics & Computers

Computers and similar electronic devices have gotten faster and smaller over the decades as computer-chip makers have learned how to shrink individual transistors. Scientists’...

Wood-Based Technology Creates Electricity from Heat

Researchers have transformed a piece of wood into a flexible membrane that generates energy from the same type of electric current (ions) on which the human body runs. This energy is generated using charged channel walls and other unique properties of the wood’s natural nanostructures. With...

Flexible, Transparent, Wearable Bio-Patch

Silicon nanoneedle patches are currently placed between skin, muscles, or tissues where they deliver exact doses of biomolecules. Commercially available silicon nanoneedle patches are usually constructed on a rigid and opaque silicon wafer. The rigidity can cause discomfort and cannot be left in the body...

Briefs: Imaging

The combination of conductive polymers on nanostructures was demonstrated as suited to creating electronic displays as thin as paper. The “paper” is similar to the Kindle tablet. It...

Q&A: RF & Microwave Electronics

Dr. Sultana won funding to advance a nanomaterial-based detector platform that can sense environmental parameters from minute concentrations of target gases and vapors, to...

Briefs: Manufacturing & Prototyping

Existing techniques for creating nano-structures are limited in what they can accomplish. Etching patterns onto a surface with light can produce 2D nano-structures but doesn’t work for 3D structures....

Briefs: Mechanical & Fluid Systems

Fast-response, stiffness-tunable (FRST) soft actuators — or movable machine elements — were developed that could be used in soft robots.

Briefs: Robotics, Automation & Control

Researchers, drawing inspiration from bacteria, have designed smart, bio-compatible microrobots that are highly flexible. Because these devices are able to swim through fluids and modify their shape...

Application Briefs: Test & Measurement

In the middle of the Pacific Ocean, Hawaii Island is surrounded by thousands of miles of thermally stable seas. The 13,796-foot Maunakea mountain summit has no nearby ranges to roil the upper...

Q&A: Nanotechnology

Texas A&M professor Jaime Grunlan and his team are developing a new flame-retardant coating using renewable, nontoxic materials readily found in nature that...

Briefs: Materials

NASA Langley Research Center has developed new methods for fabricating hollow nanoparticles using dendrimer molecules. Dendrimers are used as templates to control the size, stability, and solubility...

Briefs: Energy

A heat-rejecting film was developed that could be applied to a building’s windows to reflect up to 70 percent of the Sun’s incoming heat. The film remains highly transparent...

Briefs: Energy

Titanium is as strong as steel but about twice as light. These properties depend on the way a metal’s atoms are stacked but random defects that arise in the...

INSIDER: Imaging

Intentionally “squashing”colloidal quantum dots during chemical synthesis creates dots capable of stable, “blink-free” light emission that is fully comparable...

INSIDER: RF & Microwave Electronics

Devices that convert AC electromagnetic waves into DC electricity are known as “rectennas.” MIT Researchers have demonstrated a new kind of rectenna, that uses a flexible...
