WEST LAFAYETTE, Ind., Aug. 22, 2008 – Engineers at Purdue University have created a monolithic comb drive, a tiny motorized positioning device that could be used as a “nanoscale manipulator” that precisely moves or senses movement and forces. This device has twice the dexterity of similar devices currently being developed for applications such as biological sensors and more compact, powerful computer hard drives. According to the devices’ designer, Jason Vaughn Clark, assistant professor of electrical and computer engineering and mechanical engineering, these devices can also be used in watery environments for probing...Read full article

    metrology
    Metrology is the science and practice of measurement. It encompasses the theoretical and practical aspects of measurement, including the development of measurement standards, techniques, and instruments, as well as the application of measurement principles in various fields. The primary objectives of metrology are to ensure accuracy, reliability, and consistency in measurements and to establish traceability to recognized standards. Metrology plays a crucial role in science, industry,...
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
