Passwords Sent Securely Through the Body
“On-body” transmissions offer a more secure way to send authenticating information between a device that touches parts of the body and one confirming identity by requiring a password be entered.
New Process for Copper Nanowires
Functional nanomaterials are notoriously difficult to produce in large volumes with highly controlled composition, shapes and sizes.
Texting Replaces Voice Communications in Airport Towers
A departure clearance using voice communications can take two to three times longer than one via Data Comm—and even longer as traffic increases.
Next-Gen Hand Grenade Goes High-Tech
With the new multi-purpose grenade, soldiers have the ability to choose either fragmentation or concussive effects desired for the situation.
Room-Temperature Multiferroic Material Developed
In electronics, the advantages of multiferroics include their reversible polarization in response to low-power electric fields and the ability to hold their polarized state without continuous power.
"Phase Separation" in Oxides Could Produce a Multifunctional Chip
The ORNL proof-of-principle experiment shows that phase-separated materials could be a way beyond the “one-chip-fits-all” approach.
Virginia Tech to Use Drone Delivery
Package delivery, especially for rapid turnaround operations like food, is one of the most challenging applications of drone technology.
Mixed-Reality Technology Speeds Service Calls
Using HoloLens, service technicians will be able to visualize and identify problems with elevators ahead of a job and have hands-free access to technical and expert information when on site.
Radar-Based Imaging May Improve Avalanche Protection
The system produces 3D images that reveal how snow flows deep inside avalanches.
Brain-Sensing Technology Allows Faster Typing
The technology involves a multi-electrode array implanted in the brain to directly read signals from a region that ordinarily directs hand and arm movements.
Nanomaterial Shields Devices from Interference
A several-atoms-thick titanium carbide film can be effective at blocking and containing electromagnetic interference and can be applied easily as a coating by spraying it onto any surface.
Camera Spots Esophageal Pre-Cancers Earlier
Researchers have developed a way to take pictures of cells using a specialized camera and fluorescent light given off by a dye—offering a glimpse at what happens when good cells go bad.
Real-Time Sensor Data Used to Cut Utility Use
Many ballparks were not built with sophisticated instrumentation and control systems to closely manage water or power.
Fish Biowaste Converted to Piezoelectric Energy Harvesters
Fish scales contain collagen fibers that possess a piezoelectric property, which means that an electric charge is generated in response to applying a mechanical stress.
App Screens for Blood Conditions
HemaApp uses a smartphone camera to estimate hemoglobin concentrations and screen for anemia.
Improved Thin-Film Microelectronics
The team demonstrated room-temperature deposition of silicon and gallium nitride—linchpin elements in many advanced microelectronics.
Body Heat as a Power Source
The relatively small difference between the temperature of skin and that of the surrounding environment means it can be difficult to make use of body heat.
Stationary Antennas Nimbly Scan the Sky
University of Wisconsin–Madison electrical engineers are working out a new strategy to create antennas that spin their beams in circles while the devices stand still.
Spider Silk Used to Create Microscope Superlens
Superlenses offer the potential to allow viewing beyond current magnification limits.
Anode Boosts Charge Capacity of Batteries
In addition to tripling the charge capacity offered by graphite, the silicon-tin nanocomposite is extremely stable over many charge-discharge cycles, essentially extending its useful life.
