Leveraging Magnonic Devices

 New word to me : Magnonic.  The quanta of spin waves.    Based on the article, seems to be a useful thing. 

Feedback Algorithm Boosts Design of Magnonic Devices  By University of Vienna May 12, 2021

 Researchers at the University of Vienna and the University of Kaiserslautern have developed a method to accelerate the design of magnonic devices using a feedback-based computational algorithm.

Qi Wang, Andrii Chumak, and Philipp Pirro describe their approach in "Inverse-Design Magnonic Devices," published in Nature Communications.

The field of magnonics offers a new type of low-power information processing, in which magnons, the quanta of spin waves, carry and process data instead of electrons. A goal of the field is to create magnonic circuits which would be smaller and more energy-efficient than current electronic circuits.

Previous development approaches relied on trial and error. The proposed approach instead allows researchers to fix the parameters and objectives for the computer-designed devices. "With inverse-design one could develop neurons like the ones in our brain, but made out of magnonic elements instead," Pirro says.

Sony Launches IoT Chip

Low power, 60 mile range, but just in Japan for now.  Seems would be ideal for Smart city applications.  Most notable a new means to gather data and deliver applications remotely.

Sony built an IoT chip with a 60 mile range
It will use Sony's proprietary low-power wide area (LPWA) network launching this fall.   By Steve Dent, @stevetdent in Engadget

Sony is quietly launching a chip that could change how e-bikes, cars, street lamps and all kinds of other connected devices can relay information. The module, when installed on any IoT object, will allow it send data to Sony's proprietary low-power wide area (LPWA) ELTRES network launching this fall. It can transmit up to about 60 miles and work in noisy urban environments on objects moving at high speeds, opening up a lot of new applications in security, monitoring, tracking and more. ... "

Low Battery IOT Smart Microchip

 Quite interesting capability for IOT systems

Low battery icon NUS Engineers Invent Smart Microchip That Can Self-Start, Operate When Battery Runs Out    In AlphaGalileo

National University of Singapore (NUS) researchers have developed the BATLESS microchip, which can continue to function even when its battery is depleted. BATLESS can self-start and continue operating under dim illumination without any battery assistance via a small on-chip solar cell. This milestone reduces the size of batteries for powering Internet of Things (IoT) sensor nodes, making them 10 times smaller and less expensive to manufacture. BATLESS is able to sense, process, capture, and timestamp events of interest without interruption, and to wirelessly send such data to the cloud when the battery becomes available again. Despite being in minimum-power mode when the battery is unavailable, the lower speed of the microchip remains sufficient for many IoT applications that must sense parameters that vary slowly. BATLESS' self-starting power management method was demonstrated at 50-lux indoor light intensity, which is equal to the dim light available at twilight, and corresponds to nanoWatts of power. ... "
