Solar or photovoltaic (PV) cells fixed to roofs convert sunlight into electricity. An October Tech Brief highlighted a spin on this traditional idea of solar.
Our October Q&A in Tech Briefs highlighted an achievement from Professor Aaron Sadow of Ames Laboratory in Iowa. Sadow’s chemical process produces valuable biodegradable chemicals from discarded plastics, which are then used as surfactants and detergents in a range of applications.
Cornell Engineering Professor Khurram Afridi wants you to be able to power-up your vehicle simply by changing lanes and driving over a charging strip.
Our lead story today looked at a cutting-edge way to prepare food: Laser cooking.
Our September issue of Battery Technology highlighted rechargeable cement-based batteries that can be utilized as functional concrete. The achievement from Chalmers University of Technology, according to the battery’s developers, lays the groundwork for entire buildings that could someday...
Our “5 Ws” feature this month highlighted skin-like electronic circuits being developed at Virginia Tech.
Our Question of the Week focuses on today’s lead story – the creation of an aluminum test area that wirelessly powered lamps, fans, and cell phones.
Our August issue of Tech Briefs highlighted a technology that offers an energy-efficient alternative to the air conditioner: The Cold Tube.
An INSIDER story this month highlighted efforts from USC researchers to train artificial intelligence to imagine the unseen. The artificial-intelligence system uses the attributes that it "knows" to then think up a never-before-seen object.
An INSIDER story this month highlighted efforts to use sensors to improve the virtual design model known as a digital twin.
Our second INSIDER story today highlighted William Grover and his UC Riverside team’s efforts to swap electronics with air.
Engineers at the University of California San Diego developed a thin, flexible strip that can be worn on a fingertip and generate small amounts of electricity when a person’s finger sweats or presses on it. (Watch the demo on Tech Briefs TV.)
Our “Q&A” article in the July issue of Tech Briefs highlighted the work of Dr. Burak Ozpineci from Oak Ridge National Laboratory. Ozpineci and his team are building a wireless power-transmission system that charges an electric vehicle as it drives along the road.
A July Tech Brief highlights a “structural battery” from the Chalmers University of Technology that uses carbon fiber as a negative electrode and a lithium iron phosphate-coated aluminum foil as the positive electrode. The battery works as both a power source and as part of the main...
Cities around the world are adjusting – and in some cases overhauling – their infrastructure in an effort to cool temperatures in their areas. Los Angeles and New York City, for example, have adopted “grey infrastructure” efforts, like applying coatings to roofs and roads so that...
Our June issue of Tech Briefs highlighted a radar system that enables touch-free monitoring of heart sounds. A significant advantage offered by radar, according to the system’s inventors, is the fact that the values are recorded digitally and are thus not subjective, allowing human error to be...
One of the final hurdles to hydrogen power is securing a safe method for spotting hydrogen leaks. A sensor, featured in the June issue of Sensor Technology, has a greater sensitivity than other detectors.
Our June issue of Tech Briefs features a completely recyclable transistor from Duke University. The fully functional semiconductor is made out of three carbon-based inks that can be easily printed onto paper or other flexible, environmentally friendly surfaces.
Rectennas act a bit like your car antenna. Instead of picking up radio waves, however, the tiny optical devices absorb light and convert it into power. The rectenna featured in today’s top story, generated half a nanowatt – a small amount of power that its inventors hope to increase.
Our May issue of Tech Briefs highlighted a hybrid-electric aircraft design from MIT that, according to its creators, could reduce global nitrogen oxide (NOx) emissions by 95 percent.
Our lead story today highlighted a metal-free battery that degrades on demand. While a cobalt-less battery has its sustainability benefits, more work will need to be done for the Texas A&M-developed technology to compete with the lithium-ion standard.
Our lead story today highlighted the possible applications for a "living material" made from microalgae and cellulose.
An INSIDER story last week highlighted another recent achievement on Mars: A rover instrument known as “MOXIE” created oxygen from the Martian atmosphere. The NASA-led demonstration is a first step toward human presence on the Red Planet, according to MOXIE principal lead Michael Hecht.
An INSIDER story last week highlighted a 3D printer that uses a platform of movable pins to provide support for the created part. The invention eliminates the need for printed supports.
Taking inspiration from the butterfly, Tufts University researchers created light-activated composite devices that execute precise, visible movements and form complex three-dimensional shapes, without the need for wires or other actuating materials or energy sources.
A team from the University of Waterloo is creating robotic exoskeleton legs that use A.I. to make their own steps and control decisions. "Learning" from a collection of sample-strolls around an environment, the system adjusts its movements based on the surroundings it senses.
A Tech Brief featured in our April issue highlighted a battery-free pinpointing system from MIT called Underwater Backscatter Localization. Rather than emitting its own acoustic signals, the “UBL” reflects modulated signals from its environment. The reflections provide researchers with positioning...
This month’s Here’s an Idea episode highlighted a number of on-body sensors. Penn State professor Larry Cheng, for example, found a way to 3D-print a sensor directly on the skin (shown in the above...
A recent video on Tech Briefs TV highlighted NASA’s new idea for aircraft: the STARC-ABL. The concept under development aims to bridge the gap between current jet fuel-powered aircraft and future all-electric vehicles.
