Researchers have designed a smart fabric that can detect non-metallic objects ranging from avocadoes to credit cards, according to a study from Dartmouth College and Microsoft Research. The fabric, named Capacitivo, senses shifts in electrical charge to identify items of varying shapes and sizes.

A study and demonstration video describing the sensing system were presented at the ACM Symposium on User Interface Software and Technology (UIST 2020).

“This research has the potential to change the way people interact with computing through everyday soft objects made of fabrics,” said Xing-Dong Yang, an assistant professor of...

Breakthrough Quantum-Dot Transistors create a Flexible Alternative to Conventional Electronics

By depositing gold (Au) and Indium (In) contacts, researchers create two crucial types of quantum dot transistors on the same substrate, opening the door to a host of innovative electronics.
By depositing gold (Au) and Indium (In) contacts, researchers create two crucial types of quantum dot transistors on the same substrate, opening the door to a host of innovative electronics.

Researchers at Los Alamos National Laboratory and their collaborators from the University of California, Irvine have created fundamental electronic building blocks out of tiny structures known as quantum dots and used them to assemble functional logic circuits. The innovation promises a cheaper and manufacturing-friendly approach to complex electronic devices that can be fabricated in a chemistry laboratory via simple, solution-based techniques, and offer long-sought components for a host of innovative devices.

“Potential applications of the new approach to electronic devices based on non-toxic ...

With a training technique commonly used to teach dogs to sit and stay, Johns Hopkins University computer scientists showed a robot how to teach itself several new tricks, including stacking blocks. With the method, the robot, named Spot, was able to learn in days what typically takes a month.

By using positive reinforcement, an approach familiar to anyone who’s used treats to change a dog’s behavior, the team dramatically improved the robot’s skills and did it quickly enough to make training robots for real-world work a more feasible enterprise. The findings are newly published in a paper called, “Good Robot!”

“The question here was how ...

POSTECH Professor Byoungwoo Kang’s research team uncovers a new Li-ion battery electrode material that can achieve high-energy density and high power capability per volume without reducing particle size.

With Telsa in the lead, the electric vehicle market is growing around the world. Unlike conventional cars that use internal combustion engines, electric cars are solely powered by lithium ion batteries, so the battery performance defines the car’s overall performance...
