  • Atomic beams shoot straighter via cascading silicon peashooters
    To a non-physicist, an "atomic beam collimator" may sound like a phaser firing mystical particles. That might not be the worst metaphor to introduce a technology that researchers have now miniaturized, making it more likely to someday land in handheld devices.
  • New membrane water treatment system to reduce toxic waste and waste disposal cost by over 90 per cent
    A new pilot plant to treat industrial wastewater is being built that could potentially reduce the amount of liquid waste by over 90 per cent.
  • Putting free energy to good use with minuscule energy harvesters
    Scientists at Tokyo Institute of Technology (Tokyo Tech) have developed a micro-electromechanical energy harvester that allows for more flexibility in design, which is crucial for future IoT applications.
  • Researchers design a more durable MEMS switch
    Researchers from Binghamton University, State University of New York have developed a way to make cell phones and power lines more durable. 
  • Glassy carbon microneedles: A new transdermal drug delivery device
    Microneedles are designed to infuse medications transdermally (through the skin) and relatively painlessly during clinical applications. In a recent study, Richa Mishra and her colleagues developed a new technique to convert polymer films into a fracture-resistant glassy form of carbon to develop microneedles. The optimized transdermal drug delivery device was fabricated using photolithography to form a biocompatible and robust microneedle for pre-clinical applications.
  • Development of MEMS sensor chip equipped with ultra-high quality diamond cantilevers
    A NIMS-led research group succeeded in developing a high-quality diamond cantilever with among the highest quality (Q) factor values at room temperature ever achieved. The group also succeeded for the first time in the world in developing a single crystal diamond microelectromechanical systems (MEMS) sensor chip that can be actuated and sensed by electrical signals. These achievements may popularize research on diamond MEMS with significantly higher sensitivity and greater reliability than existing silicon MEMS.
  • Laser-pointing system could help tiny satellites transmit data to Earth
    A new laser-pointing platform developed at MIT may help launch miniature satellites into the high-rate data game.
  • How microscopic machines can fail in the blink of an eye
    How long can tiny gears and other microscopic moving parts last before they wear out? What are the warning signs that these components are about to fail, which can happen in just a few tenths of a second? Striving to provide clear answers to these questions, researchers at the National Institute of Standards and Technology (NIST) have developed a method for more quickly tracking microelectromechanical systems (MEMS) as they work and, just as importantly, as they stop working.
