Recent technological advances have enabled the development of increasingly compact and flexible devices. This includes wearable or portable technology, such as smart watches, earphones or other smart accessories, which can assist human users in a variety of ways.

Researchers at University of California, Los Angeles (UCLA) have recently devised a strategy that could enable the fabrication of portable, compact and flexible electrocaloric devices. This strategy, outlined in a paper published in Nature Energy, is based on a four-layer cascade that enables a significant temperature lift in a user’s surroundings.

“Our research started more than five years ago, when we were funded by ARPA-E, an agency of the U.S. department of energy, to solve a key cooling need: to maintain sufficient personal thermal comfort while reducing the HVAC energy consumption for offices and buildings,” Qibing Pei, one of the researchers who carried out the study, told TechXplore. “Our key goal was to create a wearable cooler.”

Artificial intelligence is being developed that can analyze whether it’s own decision or prediction is reliable.

…An AI that is aware/determine or analyze it’s own weaknesses. Basically, it should help doctors or passengers of the AI know quickly the risk involved.


How might The Terminator have played out if Skynet had decided it probably wasn’t responsible enough to hold the keys to the entire US nuclear arsenal? As it turns out, scientists may just have saved us from such a future AI-led apocalypse, by creating neural networks that know when they’re untrustworthy.

These deep learning neural networks are designed to mimic the human brain by weighing up a multitude of factors in balance with each other, spotting patterns in masses of data that humans don’t have the capacity to analyse.
