Dissolvable silicon electronics offer an unprecedented opportunity to implant advanced monitoring systems, according to researchers from the Perelman School of Medicine at the University of Pennsylvania. Implantable brain devices that literally melt away at a pre-determined rate, for...

By blending pulverized natural bone with man-made plastic, researchers at The Johns Hopkins University 3D-printed replacement skeletal structures of the head and face, including the lower jaw of a female patient. The team's composite material combines the strength and printability of plastic...

Researchers at The Massachusetts Institute of Technology (MIT), the University of Sheffield, and the Tokyo Institute of Technology have demonstrated a tiny origami robot that unfolds itself from a swallowed capsule. Steered by external magnetic fields, the bot can crawl across the stomach wall to remove...

University of Wisconsin—Madison engineers fabricated a transistor that operates at a record 38 gigahertz. The team built the high-performance device using huge rolls of flexible plastic.

NASA’s Marshall Space Flight Center has developed a unique apparatus ideal for use in nondestructive testing (NDT) of hermetic seals of containers or instrumentation. The device is capable of detecting both large and small leaks and can be calibrated to characterize the...

Traditional methods of flight flutter testing analyze system parameters such as damping levels that vary with flight conditions to monitor aircraft stability. In the past, the actual flight envelope developed for aircraft operation was essentially determined only by flight testing. The edges of...

Typically, mechanical test data has been reviewed and processed using a combination of Excel, PDF Viewer, MATLAB, and other tools. TestEVAL provides a central tool for all these tools, and enhances their capability. Having been developed in Python, it is expendable and portable. It uses no...

High-resolution submillimeter-wave spectroscopy is based on the heterodyne principle, where the incident signal is down-converted to a low intermediate frequency (IF) by nonlinear mixing with a local oscillator (LO) signal. The IF difference...

NASA has developed a novel hybrid supercapacitor system utilizing vertical graphene as an electrode material grown directly on collector metals using a plasma enhanced chemical vapor de - position. Supercapacitors are an alternative to batteries for energy storage, offering high power density and...

NASA’s Marshall Space Flight Center (MSFC) has developed compact, reconfigurable electronic devices to drive and control avionics instruments. Typical avionics systems function through centralized power distribution units (PDUs), which have complex, expensive, and time-consuming design, development, test, and...

NASA’s Langley Research Center has developed a synthetic 3D visualization flight display that presents flight data information in an intuitive way using 3D computer graphic capabilities. The flight crew can preview and...
