Novel technology aims to improve lithium metal battery life, safety
Rechargeable lithium metal batteries with increased energy density, performance, and safety may be possible with a newly-developed, solid-electrolyte interphase.
New cell-sized micro robots might make incredible journeys
Researchers have harnessed the latest nanofabrication techniques to create bug-shaped robots that are wirelessly powered, able to walk, able to survive harsh environments and tiny enough to be injected through an ordinary hypodermic needle.
3D printed smart objects with 'embodied logic'
Using stimuli-responsive materials and geometric principles, researchers have designed structures that have "embodied logic." Through their physical and chemical makeup alone, they are able to determine which of multiple possible responses to make in response to their environment.
Identifying artificial intelligence "blind spots"
A novel model developed by MIT and Microsoft researchers identifies instances in which autonomous systems have "learned" from training examples that don't match what's actually happening in the real world. Engineers could use this model to improve the safety of artificial intelligence systems, such as driverless vehicles and autonomous robots.
Process to 3D print piezoelectric materials
The piezoelectric materials that inhabit everything from our cell phones to musical greeting cards may be getting an upgrade. Researchers have developed methods to 3D print piezoelectric materials that can be custom-designed to convert movement, impact and stress from any directions to electrical energy.
3D imaging technique unlocks properties of perovskite crystals
A team of materials scientists have, for the first time, visualized the 3D atomic and electron density structure of the most complex perovskite crystal structure system decoded to date.
Shape shifting modular robot
A robot can assemble a car door or pack a box much faster and more efficiently than any human, but such single-purpose machines struggle when asked to perform in challenging environments that contain elements such as stairs or tunnels.
Wearables powered by body movements
A wearable energy-harvesting device could generate energy from the swing of an arm while walking or jogging, according to a team of researchers. The device, about the size of a wristwatch, produces enough power to run a personal health monitoring system.
Biosensor chip wirelessly detects disease
Researchers have developed a chip that can detect a type of genetic mutation known as a single nucleotide polymorphism and wirelessly send the results in real time to a smartphone, computer, or other electronic device. The chip is at least 1,000 times more sensitive at detecting an SNP than current technology.
Fiber lasers: unique tools for automotive & aerospace manufacturing
Automotive and aerospace manufacturers are increasingly turning to fiber lasers to resolve their manufacturing challenges.
Brain stimulation decreases intent to commit assault
Research shows that using minimally invasive electrical currents on the prefrontal cortex can reduce the desire to carry out physical and sexual assault and increase the perception that such violence is morally wrong.
Self-heating, fast-charging battery for electric vehicles
Californians do not purchase electric vehicles because they are cool, they buy EVs because they live in a warm climate. Conventional lithium-ion batteries cannot be rapidly charged at temperatures below 50 degrees Fahrenheit, but now a team of engineers has created a battery that can self-heat, allowing rapid charging regardless of the outside chill.
3D printing the (near) impossible with soluble supports
Since its inception in the late 1980s, 3D printing, or additive manufacturing, has been the subject of intense media attention due to the design and manufacture freedom afforded to the end user. Indeed, this freedom has become so intertwined with the concept of 3D printing that manufacturers will promote their products with the tagline that "complexity is free".
Deep learning may help predict when people need rides
Computers may better predict taxi and ride sharing service demand, paving the way toward smarter, safer and more sustainable cities, according to an international team of researchers.
Wearable helps fight addiction
WearIT is a scientific framework that uses a wearable device — such as a Fitbit or Apple watch — along with a smartphone and a web server to detect indicators of stress and/or anxiety in the person wearing the device.
