  • The power of light for internet of underwater things

    The power of light for internet of underwater things

    A system that can concurrently transmit light and energy to underwater energy devices is under development at KAUST. Self-powered internet of underwater things (IoUT) that harvest energy and decode information transferred by light beams can enhance sensing and communication in the seas and oceans. KAUST researchers are now solving some of the many challenges to this technology being employed in such harsh and dynamic environments.

  • A cyclic phosphate-based electrolyte for safe and high voltage lithium-ion batteries

    A cyclic phosphate-based electrolyte for safe and high voltage lithium-ion batteries

    In light of the ongoing shift toward renewable energy technologies and the growing number of Internet of Things (IoT) devices, researchers worldwide have been trying to develop batteries that can operate more efficiently and for longer periods of time. Lithium-ion batteries (LIBs) are currently the preferred energy-storage technology for portable electronics, as they contain organic electrolytes, which typically enable high operating voltages and energy densities.

  • Remote work will stress-test the internet—and parts will need repair, expert says

    Remote work will stress-test the internet—and parts will need repair, expert says

    With offices across the country shuttered and workers being asked to work remotely when they can, the nation is relying on the robustness of the internet and technology infrastructure as never before. To understand the issues in play, the Gazette spoke with Jim Waldo, chief technology officer for the Harvard John A. Paulson School of Engineering and Applied Sciences, professor of the practice of computer science there, and professor of technology policy at the Harvard Kennedy School. Waldo, who spent three decades in the tech industry, discussed the likelihood that parts of the all-important internet will fail, and the equal likelihood that engineers will make repairs on the fly to keep people working.

  • Fusion researchers endorse push for pilot power plant in US

    Fusion researchers endorse push for pilot power plant in US

    The growing sense of urgency around development of fusion technology for energy production in the United States got another boost this week with the release of a community consensus report by a diverse group of researchers from academia, government labs, and industry. High among its recommendations is development of a pilot fusion power plant, an ambitious goal that would be an important step toward an American fusion energy industry.

  • Cross-technology communication in the Internet of Things significantly simplified

    Cross-technology communication in the Internet of Things significantly simplified

    Whether networked vehicles that warn of traffic jams in real time, household appliances that can be operated remotely, “wearables” that monitor physical activity, or industrial plants that detect possible production errors in time and notify technical support, the number of intelligent products that communicate wirelessly with other devices in the Internet of Things (IoT) age has increased rapidly in recent years. However, not all of these devices are compatible with each other because they use different wireless technologies such as Wi-Fi, Bluetooth (low energy) or ZigBee, depending on the requirements and application. More than that, many devices often have the same radio frequencies and interfere with each other. This delays data transmission, data can be lost, energy consumption increases and battery life decreases.

  • Not all young people are ‘digital natives’ – inequality hugely limits experiences of technology

    Not all young people are ‘digital natives’ – inequality hugely limits experiences of technology

    There is a belief that younger people are fully engaged with the digital world. But I am currently leading a project exploring people’s knowledge and use of online data, and the preliminary findings from our research has found that data literacy is not uniformly high among younger people, as is often assumed. Instead, some young people have very low levels of data literacy.

  • Modernizing first responder training with VR and speech recognition

    Modernizing first responder training with VR and speech recognition

    With over 60 million American adults owning a smart speaker, human-to-machine conversation have largely become a part of a daily ritual. Though these exchanges are seemingly simple to the user, the complex technology that backs the interactions is powered by artificial intelligence, machine learning, and speech recognition. These modern machines are only continuing to grow in popularity, and for many Americans, voice recognition technology is becoming as natural as owning a smartphone. The user interfaces that drive the functionality of smart speakers have brought new and improved convenience to modern-day Americans. By the same token, this capability has the potential to alleviate burdens from the operations of our nation’s first responders.
