  • Researchers 3-D print electronics and cells directly on skin April 25, 2018
    In a groundbreaking new study, researchers at the University of Minnesota used a customized, low-cost 3D printer to print electronics on a real hand for the first time. The technology could be used by soldiers on the battlefield to print temporary sensors on their bodies to detect chemical or biological agents or solar cells to […]
  • Electrode shape improves neurostimulation for small targets April 24, 2018
    A cross-like shape helps the electrodes of implantable neurostimulation devices to deliver more charge to specific areas of the nervous system, possibly prolonging device life span, says research published in March in Scientific Reports.
  • Screen reader plus keyboard helps blind, low-vision users browse modern webpages April 18, 2018
    Browsing through offerings on Airbnb means clicking on rows of photos to compare options from prospective hosts. This kind of table-based navigation is increasingly central to our digital lives - but it can be tedious or impossible for people who are blind or have low vision to navigate these modern webpages using traditional screen readers.
  • Researchers conduct first-ever combustion experiment with X-rays April 13, 2018
    The U.S. Army Research Laboratory's Center for Unmanned Aircraft Systems Propulsion made an historic first with its experiment in a gas turbine combustor using X-rays. The data will help advance gas turbine engine designs for higher power density and efficiency, scientists said.
  • Engineers build smallest volume, most efficient wireless nerve stimulator April 10, 2018
    In 2016, University of California, Berkeley, engineers demonstrated the first implanted, ultrasonic neural dust sensors, bringing closer the day when a Fitbit-like device could monitor internal nerves, muscles or organs in real time. Now, Berkeley engineers have taken neural dust a step forward by building the smallest volume, most efficient wireless nerve stimulator to date.
  • First dynamic spine brace—robotic spine exoskeleton—characterizes spine deformities April 9, 2018
    Spine deformities, such as idiopathic scoliosis and kyphosis (also known as "hunchback"), are characterized by an abnormal curvature in the spine. The children with these spinal deformities are typically advised to wear a brace that fits around the torso and hips to correct the abnormal curve. Bracing has been shown to prevent progression of the […]
  • Earwigs and the art of origami March 22, 2018
    ETH Zurich researchers have developed multifunctional origami structures, which they then fabricated into 4-D printed objects. The design principle mimics the structure of an earwig's wing.
  • Depth-sensing imaging system can peer through fog March 21, 2018
    MIT researchers have developed a system that can produce images of objects shrouded by fog so thick that human vision can't penetrate it. It can also gauge the objects' distance.
  • Study shows electrically charging planes have reduced risk of being struck by lightning March 9, 2018
    Aviation experts estimate that every commercial airplane in the world is struck by lightning at least once per year. Around 90 percent of these strikes are likely triggered by the aircraft itself: In thunderstorm environments, a plane's electrically conductive exterior can act as a lightning rod, sparking a strike that could potentially damage the plane's […]
  • Researchers develop optical tools to detect metabolic changes linked to disease March 7, 2018
    Metabolic changes in cells can occur at the earliest stages of disease. In most cases, knowledge of those signals is limited, since we usually detect disease only after it has done significant damage. Now, a team led by engineers at Tufts University School of Engineering has opened a window into the cell by developing an […]
