Research from North Carolina State University and Carnegie Mellon University shows that passing wireless power transfer through a magnetic resonance field enhancer (MRFE) – which can be as simple as a copper loop – can boost the transfer efficiency by at least 100 percent as compared to transferring through air alone. MRFE use could potentially […]
Multiferroic Materials & Devices Integrated with Silicon Chips
A research team led by North Carolina State University has made two advances in multiferroic materials, including the ability to integrate them on a silicon chip, which will allow the development of new electronic memory devices. The researchers have already created prototypes of the devices and are in the process of testing them. Multiferroic materials […]
Impacts of Power Prosthetic Failures on Amputees
Powered lower limb prosthetics hold promise for improving the mobility of amputees, but errors in the technology may also cause some users to stumble or fall. New research examines exactly what happens when these technologies fail, with the goal of developing a new generation of more robust powered prostheses. “My work has focused on developing […]
New Method for Building Flexible Devices
Researchers from North Carolina State University have developed a new way to transfer thin semiconductor films, which are only one atom thick, onto arbitrary substrates, paving the way for flexible computing or photonic devices. The technique is much faster than existing methods and can perfectly transfer the atomic scale thin films from one substrate to […]
New Materials Yield Record Efficiency Polymer Solar Cells
Researchers from North Carolina State University and Hong Kong University of Science and Technology have found that temperature-controlled aggregation in a family of new semi-conducting polymers is the key to creating highly efficient organic solar cells that can be mass produced more cheaply. Their findings also open the door to experimentation with different chemical mixtures […]
Electric drive vehicles have little impact on emissions
A new study from North Carolina State University indicates that even a sharp increase in the use of electric drive passenger vehicles (EDVs) by 2050 would not significantly reduce emissions of high-profile air pollutants carbon dioxide, sulfur dioxide or nitrogen oxides. “EDVs” is a catch-all term that includes hybrid, plug-in hybrid and battery electric vehicles. […]
Finding Ways to Minimize Power Grid Disruptions from Wind Power
Researchers from North Carolina State University and Johns Hopkins University have found that an increase in the use of wind power generation can make the power grid more fragile and susceptible to disruptions. But the researchers didn’t just identify the problem – they have also devised a technique for coordinating wind power generation and energy […]
New approach advances wireless power transfer for vehicles
Researchers from North Carolina State University have developed new technology and techniques for transmitting power wirelessly from a stationary source to a mobile receiver – moving engineers closer to their goal of creating highway “stations” that can recharge electric vehicles wirelessly as the vehicles drive by. “We’ve made changes to both the receiver and the […]
