From the biggest bridges to the smallest medical implants, sensors are everywhere, and for good reason: The ability to sense and monitor changes before they become problems can be both cost-saving and life-saving.
To better address these potential threats, the Intelligent Structural Monitoring and Response Testing (iSMaRT) Lab at the University of Pittsburgh Swanson School of Engineering has designed a new class of materials that are both sensing mediums and nanogenerators, and are poised to revolutionize the multifunctional material technology big and small. ....

As electrification advancement accelerates and more renewables are integrated into the electric grid, improved power electronics systems are needed to convert AC or DC power into a usable form. New semiconductor device materials and advanced magnetic materials can enable an unprecedented combination of voltage levels and power handling capabilities.
However, the latest class of new switching devices, which use so-called ultra-wide bandgap (UWBG) semiconductor materials, will also require improved soft magnetic materials and manufacturing approaches not currently available. ....
