  • 3-D Conductive Structures Built with Liquid Metal

    Engineers at North Carolina State University in Raleigh developed techniques to build three-dimensional objects with electrical conductivity from liquid metal at room temperature. A team from the lab of chemical engineering professor Michael Dickey published its findings online last week in the journal Advanced Materials. The NC State researchers devised a series of methods using…

  • PET/MRI Scanning Technique Devised to Track 3-D Motion

    Update, 25 July 2013. We learned today that Jinsong Ouyang at Mass General Hospital is the principal investigator on the project and led the research, not Chuan Huang, who presented the findings. Others working on the project include Jerome Ackerman, Yoann Petibon, Thomas Brady, and Georges El Fakhri. Researchers at Massachusetts General Hospital and Harvard…

  • Inkjet Printing Process Devised for Graphene Circuits

    Materials scientists at Northwestern University in Illinois developed an ink made of a graphene solution that can print patterns for electronic circuits and maintain their conductivity even after folding. The team led by engineering professor Mark Hersam published its findings online in a recent issue of the Journal of Physical Chemistry Letters (paid subscription required).…

  • Tiny, Winged Manueverable Robotic Insects Created, Tested

    Engineers at Harvard University in Massachusetts developed robotic insects with flapping wings, using a microfabrication process that makes it possible to produce these devices in large numbers. The team from Harvard’s School of Engineering and Applied Sciences and Wyss Institute for Biologically Inspired Engineering, led by engineering professor Robert Wood, published its findings in this…

  • Insect Eyes Inspire Multiple Digital Camera Lens Design

    Engineers at University of Illinois in Urbana designed a new type of digital camera lens based on the multiple-lens design found in the eyes of bees and dragonflies. The team led by Illinois engineering professor John Rogers, with colleagues from the U.S., Korea, Singapore, and China published their findings in this week’s issue of the…

  • Lab-On-A-Chip Diagnoses Multiple Tropical Diseases

    The Agency for Science, Technology and Research (A*STAR), Singapore’s main science funding agency, and Singapore clinical chip manufacturer Veredus Laboratories unveiled a new automated lab-on-a-chip device that can diagnose 13 tropical diseases from a single blood sample. Veredus is a subsidiary of STMicroelectronics specializing in medical diagnostics. The partnership between A*Star and Veredus that developed…

  • Low Cost Soft-Touch Robotic Sensor Circuits Commercialized

    Computer scientists at Harvard University developed and are taking to market circuits for robotic devices and potentially other electronic products that can sense the slightest application of pressure. The team led by Ph.D. candidate Leif Jentoft and postdoctoral fellow Yaroslav Tenzer in Harvard’s Biorobotics Laboratory started a company to commercialize the technology, and are licensing…

  • Optical Circuits Developed with Semiconductor Diamonds

    Engineers at Karlsruhe Institute of Technology and colleagues in Germany developed an economical method to harness polycrystalline diamonds for optical circuits. The team led by nanotechnology lab director Wolfram Pernice published its findings earlier this week in the journal Nature Communications (paid subscription required). Optical circuits work like integrated electronic circuits, but instead of transmiting…

  • Injectable LEDs Developed to Study Brain Functions

    Biomedical engineers at University of Illinois in Champaign, with colleagues from Washington University in St. Louis, and other institutions in the U.S., Korea, and China developed tiny light-emitting diode (LED) devices that can be injected deep in the brain to study neural functions. The team led by Illinois’s John Rogers published its findings in this…

  • Gallium Arsenide Nanowires Boost Solar Cell Efficiency

    University and industrial researchers in Switzerland and Denmark developed a new type of solar cell that in lab tests captures more light and generates more power than traditional silicon cells. The team from Ecole Polytechnique Fédérale de Lausanne (EPFL) in Lausanne, Switzerland, Neils Bohr Institute at University of Copenhagen, and the Danish spin-off company SunFlake A/S…
