Infrared motion detectors can cover only a limited amount of space, a person has to be within the detector's line of sight to be detected, and lights can go off when a person remains still...
Briefs: Robotics, Automation & Control
Soft, 3D-printed structures have been created whose movements can be controlled with a wave of a magnet, much like marionettes without the strings. The structures that can be magnetically manipulated...
Briefs: Mechanical & Fluid Systems
Check valves are traditionally designed as a simple poppet/spring system where the spring is designed to equal the force created from the sealing area of the valve seat multiplied by the...
Briefs: Mechanical & Fluid Systems
Lamina emergent compliant mechanisms (including origami-adapted compliant mechanisms) are mechanical devices that can be fabricated from a planar material (a lamina) and have motion that...
Briefs: Aerospace
Painting of surfaces having numerous facets and/or curved surfaces is a time-consuming process that requires the application of several coats (layers) of paint. Such surfaces are often found on...
Briefs: Medical
Researchers have developed a customizable soft robot that fits around a heart and helps it beat, potentially opening new treatment options for people suffering from heart failure.
Briefs: Semiconductors & ICs
Pulsed laser vaporization (PLV) production of single-wall carbon nanotubes (SWNTs) on traditional Co/Ni catalyst was explored with respect...
Briefs: Manufacturing & Prototyping
A technique was developed that uses a specially adapted 3D printer to build therapeutic biomaterials from multiple materials. The advance could be a step toward on-demand printing of complex...

Composite Material Cools Itself Down Under Extreme Temperatures
A material, inspired by nature, can regulate its own temperature and could be used to treat burns and help space capsules withstand atmospheric forces. The research used a network of multiple microchannels with active flowing fluids (fluidics) as a method and proof-of-concept to...
Briefs: Materials
3D printing allows for the efficient manufacture of complex geometries. A very promising method is direct laser writing in which a computer-controlled focused laser beam acts as a pen and produces the desired...
Briefs: Materials
In biology, there are many examples where light induces movement or change — think of flowers and leaves turning toward sunlight. Magnetic elastomeric composites were developed that move in different ways...
Briefs: Test & Measurement
Automated Fiber Placement (AFP) machines can be susceptible to tow-tape defects such as gaps and overlaps. These can reduce strength between 7% and 32%....
Briefs: Electronics & Computers
Innovators at NASA's Glenn Research Center have expanded their growing portfolio of aerogels to include a new optically transparent polyimide aerogel. Aerogels — low-density, highly porous, ultralight...
Briefs: Electronics & Computers
Lasers play roles in many manufacturing processes, from welding car parts to crafting engine components with 3D printers. To control these tasks, manufacturers must ensure that their lasers fire at the...
