  • Scientist modifies digital cinema technology for future space missions
    Rochester Institute of Technology researchers are developing and testing an astronomical imager inspired by an Oscar-award winning cinema projection system.
  • A flexible, low-cost technique could lead to the mass production of microelectromechanical systems
    Making increasingly smaller microelectromechanical systems (MEMS) has proved very challenging, limiting their anticipated potential. Now, researchers at A*STAR have developed a versatile and cost-effective technique for making devices with much greater precision and reliability for use in biotechnology and medical applications.
  • New approach to measuring stickiness could aid micro-device design
    Brown University engineers have devised a new method of measuring the stickiness of micro-scale surfaces. The technique, described in Proceedings of the Royal Society A, could be useful in designing and building micro-electro-mechanical systems (MEMS), devices with microscopic moving parts.
  • Engineering team develops radiation-resistant computers capable of high-performance computing in the harshness of space
    In T minus 8,760 hours, or roughly one year, the Space Test Program-Houston 6 (STP-H6) hybrid and reconfigurable space supercomputer will board the International Space Station. The newest mission to the ISS featuring research and technology from the University of Pittsburgh's NSF Center for Space, High-performance, and Resilient Computing (SHREC) will bring an unprecedented amount of computing power into space and invaluable research opportunities from the ground station on Pitt's Oakland campus.
  • A marriage of light-manipulation technologies
    Researchers have, for the first time, integrated two technologies widely used in applications such as optical communications, bio-imaging and Light Detection and Ranging (LIDAR) systems that scan the surroundings of self-driving cars and trucks.
  • MEMS chips get metatlenses
    Lens technologies have advanced across all scales, from digital cameras and high bandwidth in fiber optics to the LIGO lab instruments. Now, a new lens technology that could be produced using standard computer-chip technology is emerging and could replace the bulky layers and complex geometries of traditional curved lenses.
  • High-sensitivity low-power MEMS accelerometer for detecting extremely weak ground and building vibrations
    Hitachi Ltd. today announced the development of a high-sensitivity low-power MEMS accelerometer that can detect extremely weak ground and building vibrations by combining sophisticated MEMS technology with circuit technology. The sensor achieves a comparable sensitivity to that of sensors for oil & gas exploration (noise level 30ng/√Hz) with less than half the power consumption (20mW). Hitachi intends to apply this sensor to various applications including next generation oil & gas exploration, and infrastructure monitoring, to contribute to the realization of a comfortable, safe and secure society.
  • Optically tunable microwave antennas for 5G applications
    Multiband tunable antennas are a critical part of many communication and radar systems. New research by engineers at the University of Bristol has shown significant advances in antennas by using optically induced plasmas in silicon to tune both radiation patterns and operation frequency.
