New electronic “skin” could lead to lightweight night-vision glassesMIT engineers have developed a technique to grow and peel ultrathin “skins” of electronic material that could be used in wearable sensors, flexible transistors and computing elements, and sensitive compact imaging devices. Technology makes pesticides stick to plant leavesA new pesticide application system developed by MIT researchers and their spinoff company could significantly cut use of pesticides and fertilizers, saving farmers money and reducing polluting runoff. New printable metamaterials that are both strong and stretchy could allow fabrication of bendable ceramics, glass, and metals. These tough yet bendy materials could be made into tear-resistant textiles, flexible semiconductors, electronic chip packaging, and durable yet compliant scaffolds on which to grow cells for tissue repair.
