Briefs: Materials
Used since 2013, electroceutical bandages — which use electrical impulses to treat medical issues — kill bacteria around a wound, allowing wounds to heal faster. In addition, if infection is...
Briefs: Mechanical & Fluid Systems
Researchers have developed a fundamentally new type of rotary electrical contact that addresses the two limitations of conventional brush/slip ring technology: 1) short operating lifetime due to sliding-contact wear,...
Briefs: Energy
Metal-air batteries are one of the lightest and most compact types of batteries but when not in use, they degrade quickly, as corrosion eats away at their metal electrodes. While...
Briefs: Materials
Increase in bioethanol production throughout the US has led to an increase in the process coproduct — distiller’s grains with solubles (DGS). DGS can be used to feed...
Briefs: Electronics & Computers
Directly converting electrical power to heat is easy; however, converting heat into electrical power is not as easy. To address this issue, a tiny silicon-based device was developed that can harness...
Briefs: Electronics & Computers
Conventional electrolytes used in lithium-ion batteries that power household electronics like computers and cellphones are not suitable for lithium-metal batteries....

Double-Fed Induction Linear Alternator
This technology was developed to address the limitations of traditional, single-fed linear alternators that require permanent magnets, adhesive bonding organics, and heavy iron laminations for flux control. They experience eddy-current losses and require electromagnetic interference protection. Furthermore,...
Briefs: Energy
Lithium batteries allow electric vehicles to travel several hundred miles on one charge. Their capacity for energy storage is well known — so is their tendency to occasionally catch...
Articles: Sensors/Data Acquisition
This column presents technologies that have applications in commercial areas, possibly creating the products of tomorrow. To learn more about each technology, see the contact information provided for that innovation.
Briefs: Materials
Traditionally, electronics are cooled using a heat sink that transfers the heat generated by the electronic system into the air or a liquid coolant. For the heat sink to work, it has to be...
Articles: Mechanical & Fluid Systems
We recently had a discussion with Sri Peruvemba, VP of Strategy at BeBop Sensors (Berkeley, CA), about the technology and applications for their two-dimensional fabric sensor material. I started by asking Sri...
Briefs: Electronics & Computers
Batteries with metallic lithium anodes offer enhanced efficiency compared to conventional lithium-ion batteries because of their higher capacity. However, safety concerns and a short lifespan stand in the way. To...

Who
Manufacturers across medical, space, aviation, military, and automotive industries could use the technology to build complex machines that integrate with surfaces to be very compact, but can deploy to do...
NASA Spinoff: Test & Measurement
Rocket engine testing requires a lot of light since all tests are filmed with high-speed cameras to monitor performance; however, those cameras have to adjust to the bright plume from a firing...
Briefs: Materials
Anew material was developed that can extract the key ingredient in the most common form of plastic from a mixture of other chemicals while consuming far less energy than usual. The...

A new 3D printed device turns snowfall into electricity.
Products: Software
nanotron, Munich, Germany, introduced 360° Edge Analytics tools and location-aware wireless sensors for manufacturing and healthcare. The products automatically extract event information in real time. Position data is...
Briefs: Photonics/Optics
Many devices use light to probe the quantum states of atoms in a vapor confined in a small cell. Atoms can be highly sensitive to external conditions, and therefore make superb detectors. Devices...
Briefs: Nanotechnology
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...
