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.
Textile Generates Power from Sun and Motion
Researchers used a commercial textile machine to weave together solar cells constructed from light-weight polymer fibers with fiber-based triboelectric nano-generators.
Textile Generates Power from the Sun and Motion
Researchers used a commercial textile machine to weave together solar cells constructed from light-weight polymer fibers with fiber-based triboelectric nano-generators.
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.
Chemical Extraction Method Could Recover Gold
The finding could help salvage an estimated 300 metric tons of gold from e-waste.
Device Could Boost Energy Storage Capacity by 10x
The device reportedly recharges in seconds, has a long life, and operates near 100% efficiency.
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.
Biosensor Allows for Early Detection of Prostate Cancer
The biosensor's high sensitivity makes it capable of early detection of the molecules that are produced by the cancer that pass into the bloodstream.
Underground Radar for Post-Katrina Damage
The technology is a pipe-penetrating scanning system that uses ultra-wide-band pulsed radar.
Plasma Etching of Biochar Reduces Supercapacitor Costs
The ability to absorb and discharge energy quickly makes supercapacitors integral to energy harvesting.
Brain-Machine Interface Triggers Recovery
WAP says theirs is the first study to report that long-term brain-machine interface use could lead to significant recovery of neurological function in patients suffering from severe spinal cord injuries.
Nanocrystal-generated Light Could Speed Communications
White light generated using semiconductor lasers may one day replace LED white-light bulbs for energy-efficient lighting, researchers say.
