Scientists have used a compound made from a starch derivative and baking soda to help convert mechanical to electrical energy. The approach, developed by scientists at Daegu Gyeongbuk Institute of Technology (DGIST), with colleagues in Korea and India, is cost-effective and biocompatible, and can help charge low-energy electronics like calculators and watches. The details were published in the journal Advanced Functional Materials.

“Triboelectric nanogenerators harvest mechanical energy and convert it into an electric current,” explains DGIST robotics engineer Hoe Joon Kim...

Quantum computers developed to date have been one-of-a-kind devices that fill entire laboratories. Now, physicists at the University of Innsbruck have built a prototype of an ion trap quantum computer that can be used in industry. It fits into two 19-inch server racks like those found in data centers throughout the world. The compact, self-sustained device demonstrates how this technology will soon be more accessible.

Over the past three decades, fundamental groundwork for building quantum computers has been pioneered at the University of Innsbruck, Austria...

Engineers have developed an integrated circuit that can carry out complicated artificial-intelligence operations like face, voice and gesture recognition and cardiac monitoring. Powered by either a tiny battery or a solar panel, it processes data at the edge and can be configured for use in just about any type of application.

AI is used in an array of extremely useful applications, such as predicting a machine’s lifetime through its vibrations, monitoring the cardiac activity of patients and incorporating facial recognition capabilities into video surveillance systems. The downside is that AI-based technology generally requires a lot of power and, in most cases, must be permanently connected to the cloud, raising issues related to data protection, IT security and energy use.

Material could be used in future quantum computing applications. An international team of physicists led by the University of Minnesota has discovered that a unique superconducting metal is more resilient when used as a very thin layer. The research is the first step toward a larger goal of understanding unconventional superconducting states in materials, which could possibly be used in quantum computing in the future.
