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,...

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...

An Ohio State researcher shares with Tech Briefs the promise of potassium-oxygen batteries.
Three new unmanned helicopters were unveiled at AUVSI’s XPONENTIAL show in Chicago.

Measurement Method for Radioactive Methane

Anew method for measuring radioactive methane is an optical one based on spectroscopy. Previously, radioactive methane has been measured with accelerator mass spectrometry involving expensive machines. Optical measuring could be a cheaper and more agile method.

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...

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....

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...

Improving Vehicle Fuel Economy with ADAS

Fuel economy is a key factor in worldwide energy-consumption. One way to improve fuel economy is using driver feedback to promote efficient habits (eco-driving). Emerging research is looking into...

This invention applies to the field of sputtering, depositing SiGe thin films on sapphire substrates. It is a method of modifying the film...

A new 3D printed device turns snowfall into electricity.

Recent technical advances have enabled flywheel energy storage systems (FESS) to become more compact and able to support higher-power applications. Due to their proven...

Wearable biosensors for health monitoring lack a lightweight, long-lasting power supply. A new method was developed for making a charge-storing system that is easily integrated into...

Growing demand for electric vehicles and more sustainable forms of transport means finding new forms of energy storage such as batteries, supercapacitors, and fuel cells. Currently, a major...

The first mass-produced electric vehicles (EVs) hit the road late in 2010 with the introduction of the Nissan Leaf, which remains the world’s top-selling,...

Who

Millions of people who rely on pacemakers, defibrillators, and other livesaving implantable devices powered by batteries that need to be replaced every five to 10 years.

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...

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...

Thin, durable heating patches were created using intense pulses of light to fuse tiny silver wires with polyester. Their heating performance is nearly 70 percent higher than similar patches. The inexpensive...

Researchers at NASA’s Marshall Space Flight Center have developed a new dielectric material based on barium titanate nanopowder processed via spark plasma sintering (SPS). The rapid and...

Chip Measures Quantities with Quantum Precision

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....

The MIT system can monitor the behavior of electronic devices within a building, a factory – and even a 270-foot Coast Guard cutter.
A new technology may lead to a more mainstream use of algal biofuels.
Question of the Week: Automotive
Will Carbon Fibers Find a New Place in Vehicles?

In a Tech Briefs article last week, Virginia Tech professor Greg Liu spoke about his team’s newly developed porous carbon fibers, and how the material may someday change how vehicles are built and powered.

Fuel Cell/Fuel Cell Hybrid System

Fuel cells can deliver clean, reliable, and uninterrupted power nearly 100 percent of the time. Fuel cells offer the advantage of efficiency by converting chemical energy directly to electricity. They have no moving parts, thereby eliminating failures associated with pumps, blowers, heat exchangers, and other...
