Breakthrough in 3D printed marine grade stainless steel

Researchers have achieved a breakthrough in 3D printing one of the most common forms of marine grade stainless steel - a low-carbon type called 316L - that promises an unparalleled combination of high-strength and high-ductility properties for the ubiquitous alloy.

Novel circuit design boosts wearable thermoelectric generators

Using flexible conducting polymers and novel circuitry patterns printed on paper, researchers have demonstrated proof-of-concept wearable thermoelectric generators that can harvest energy from body heat to power simple biosensors for measuring heart rate, respiration or other factors.

Robotic system monitors specific neurons

Recording electrical signals from inside a neuron in the living brain can reveal a great deal of information about that neuron's function and how it coordinates with other cells in the brain.

Defeating cyberattacks on 3D Printers

With cyberattacks on 3D printers likely to threaten health and safety, researchers have developed novel methods to combat them, according to a groundbreaking study.

Spray-on electric rainbows: making safer electrochromic inks

Anyone who has a rear-view mirror that automatically dims blue in reaction to annoying high-beam headlights glaring from behind has seen an electrochromic film in action. Now, chemists have developed a new method to more safely and, by extension, easily produce these shear films, which change their color with the help of a tiny electric current. This could make them available to many industries that have not been able to feasibly use them before.

Be your own battery

Researchers are developing a revolutionary technology that will allow people to act as their own "power source" by wearing clothing such as "smart" shirts and shoes that harvest and store electricity.

Nanogenerators that stand the test of time

Earlier this month, IDTechEx analysts were invited to attend the second talk within the "From Discovery Science to Industrial Application" series, co-organised by the Cambridge Network and the Maxwell Centre.

Robot uses deep learning and big data to write and play its own music

A marimba-playing robot with four arms and eight sticks is writing and playing its own compositions in a lab at the Georgia Institute of Technology. The pieces are generated using artificial intelligence and deep learning.

Liquid tin-sulfur compound shows thermoelectric potential

Glass and steel makers produce large amounts of wasted heat energy at high temperatures, but solid-state thermoelectric devices that convert heat to electricity either don't operate at high enough temperatures or cost so much that their use is limited to special applications such as spacecraft.

Research aims to make artificial intelligence explain itself

Eight computer science professors in Oregon State University's College of Engineering have received a $6.5 million grant from the Defense Advanced Research Projects Agency to make artificial-intelligence-based systems like autonomous vehicles and robots more trustworthy.

Sewbots brings manufacturing closer to home

The company's patented computer vision systems view fabric more accurately than the human eye, tracking exact needle placement to within half a millimeter of accuracy.

Swarming robots and autonomous blimps

Researchers have created a team of free-flying robots that obeys the two rules of the air: don't collide or undercut each other. They've also built autonomous blimps that recognize hand gestures and detect faces.

More efficient, faster technique to remotely operate robots

The traditional interface for remotely operating robots works just fine for roboticists. They use a computer screen and mouse to independently control six degrees of freedom, turning three virtual rings and adjusting arrows to get the robot into position to grab items or perform a specific task.

Swarms of autonomous aerial vehicles test new dogfighting skills

Aerial dogfighting began more than a century ago in the skies over Europe with propeller-driven fighter aircraft carried aloft on wings of fabric and wood. An event held recently in southern California could mark the beginning of a new chapter in this form of aerial combat.

Tarzan robot hangs above crops to inspect plants as they grow

With robots dangling over the field, researchers will be able to get more frequent measurements and to avoid some laborious field work. Someday, they may be able to stay at their laptops miles away, in the air conditioning, scanning a steady stream of images and data sent back from the robots.

New 3-D printing method creates shape-shifting objects

A team of researchers has developed a new 3-D printing method to create objects that can permanently transform into a range of different shapes in response to heat.

Brake and tire dust kill too: Escape routes

Though tailpipe emissions will fall in the years ahead as more zero-emission vehicles hit the streets and old vehicles are retired, one major source of highway air pollution shows little sign of abating: brake and tire dust.

Nanofiber marks important step in next generation battery development

One of the keys to building electric cars that can travel longer distances and to powering more homes with renewable energy is developing efficient and highly capable energy storage systems.

New low-cost technique converts bulk alloys to oxide nanowires

A simple technique for producing oxide nanowires directly from bulk materials could dramatically lower the cost of producing the one-dimensional nanostructures. That could open the door for a broad range of uses in lightweight structural composites, advanced sensors, electronic devices - and thermally-stable and strong battery membranes able to withstand temperatures of more than 1,000 degrees Celsius.

Army researchers demonstrate 3-D printed drones

Soldiers witnessed the innovation of Army researchers recently during flight testing of 3-D printed unmanned aircraft systems that were created on-demand for specific missions.
