  • Ultra-Light Robotic Insect Uses Soft Artificial Muscles to Move – Survives Being Flattened by a Fly Swatter

    Ultra-Light Robotic Insect Uses Soft Artificial Muscles to Move – Survives Being Flattened by a Fly Swatter

    An untethered model that is fully wireless and autonomous, weighing less than 1 gram and carrying its battery and all electronic components on its back. Credit: EPFL Researchers at EPFL have developed an ultra-light robotic insect that uses its soft artificial muscles to move at 3 cm per second across different types of terrain. It can be folded or crushed and yet continue to move. Imagine swarms of robotic insects moving around us as they perform various tasks. It might sound like science fiction, but it’s actually more plausible than you might think. Researchers at EPFL’s School of Engineering have developed a soft robotic insect, propelled at 3 cm per second by artificial muscles. The team developed two versions of…

    3D Printing Tiny, Ultraprecise Parts for Massive Impact

    Boston Micro Fabrication’s machines use a technology co-developed by MIT Professor Nicholas Fang to print millimeter-sized products with details at the micron scale. Credit: courtesy of BMF Technologies Professor Nicholas Fang’s startup Boston Micro Fabrication uses a novel light-focusing method to make ultraprecise printers. Whether it’s computer chips, smartphone components, or camera parts, the hardware in many products is constantly getting smaller. The trend is pushing companies to come up with new ways to make the parts that power our world. Enter Boston Micro Fabrication (BMF). The company was co-founded by MIT Professor Nicholas Fang in 2016 to improve the resolution and precision of 3D printing. Today BMF is helping customers in the race toward ever smaller parts by offering…

  • Testing at the World’s Largest Indoor Ice Tank Shows Warm Ice May Fracture Differently Than Cold Ice

    Testing at the World’s Largest Indoor Ice Tank Shows Warm Ice May Fracture Differently Than Cold Ice

    The displacement measuring instruments at Aalto University’s Ice Tank, the largest of its kind in the world, detect the crack opening to the level of microns. In this image the crack has split the ice completely into two pieces. Credit: Iman El Gharamti/Aalto University New study suggests old rules on how ice breaks may not always hold up. Researchers at Aalto University have found strong evidence that warm ice – that is, ice very close in temperature to zero degrees Celsius – may fracture differently than the kinds of ice typically studied in laboratories or nature. A new study published in The Cryosphere takes a closer look at the phenomenon, studied at the world’s largest indoor ice tank on Aalto’s…

  • “Linchpin” for Tackling Climate Change: Store Up the Sun

    “Linchpin” for Tackling Climate Change: Store Up the Sun

    Molten metal. Asegun Henry has a big idea for tackling climate change: Store up the sun. “This is the key, the linchpin that will set a lot of things in the right direction,” says the MIT mechanical engineering professor. Asegun Henry has a bold idea to save the world. He believes the key to reducing carbon emissions, and mitigating further climate change, lies in our ability to box up the sun. Today, much of the renewable energy that’s captured from the wind and sun is delivered in a use-it-or-lose-it capacity. To store such energy, Henry envisions a completely sustainable, zero-carbon grid with the potential to supply all our electrical needs, even on overcast and windless days. And he has a…

  • 5D Imaging of Ultrafast Phenomena With Spectral-Volumetric Compressed Ultrafast Photography

    5D Imaging of Ultrafast Phenomena With Spectral-Volumetric Compressed Ultrafast Photography

    Snapshot of five-dimensional imaging with temporal-spatial-spectral resolutions. Credit: S. Zhang, East China Normal University Spectral-volumetric compressed ultrafast photography simultaneously captures 5D information in a single snapshot. Information-rich optical imaging can provide multidimensional information to enable observation and analysis of a detected target, contributing insights into mysterious and unknown worlds. With its ability to capture dynamic scenes on picosecond—and even femtosecond—timescales, ultrafast multidimensional optical imaging has important applications in the detection of the ultrafast phenomena in physics, chemistry, and biology. While pump-probe-based ultrafast imaging can acquire high-resolution multidimensional information, it cannot adequately capture unstable or irreversible transient scenes. Fortunately, compressed ultrafast photography (CUP), based on compressed sensing and streak imaging, surpasses traditional pump-probe-based ultrafast imaging. CUP has attracted broad attention due…
