Flexible Supercapacitor May Enable Phone Charging in Seconds
Researchers have developed a process for making flexible supercapacitors that can be recharged more than 30,000 times without degrading.
Fluorescent Dye Can Stockpile Energy
A fluorescent liquid dye, BODIPY, has stored and transferred energy in a rechargeable liquid battery.
WiFi Radio Advance Could Benefit IoT
The device has a range of about 50 meters and can transmit up to 300 kilobits per second.
Wearable Terahertz Scanner Made with Carbon Nanotubes
Applications in industrial as well as medical non-invasive imaging are envisioned for the flexible, portable device.
Smart Cities for the Golden Years
Smart City technologies have the potential to enable the disabled and elderly to remain independent for longer, and live healthy, mobile lives. Standards are being developed to help meet these goals.
Method to Dissipate Heat in Electronic Devices
An international team of scientists has modified the energy spectrum of acoustic phonons by confining them to nanometer-scale semiconductor structures.
Network Traffic Visualization Tool Could Help Thwart Cyber Attacks
Researchers have created a tool that allows for the visualization of network traffic so administrators can more readily grasp the "big picture" during a cyber event.
Traveling Over the Holidays? RFID Could Help
Improvements in baggage handling rates may not have to come at a significant cost.
Engineer’s Guide to Copper vs. Fiber
An efficient modular infrastructure is required to adapt to fast-moving business requirements, increasing port and cable densities, and rapid deployment needs. But which to use: copper or fiber?
Finger Vein Authentication Uses Smartphone Camera
The advantage of finger vein authentication is that the characteristics used for biometric identification are in vivo, making it more difficult to forge or spoof.
Researchers to Test Energy-harvesting Computers with Satellites
The systems were developed to counter the fact that while radio waves, solar energy, heat, and vibrations can power devices, harvested energy can lead to periodic power failures and unreliable behavior.
"Clever Buoy" Uses Sonar and Software to Warn of Sharks
The system uses multibeam sonar transducers that are mounted on the ocean floor, together with custom detection software, to scan for shark-like objects.
The Lowest Vehicular Emissions? Batteries vs. Fuel Cells
The future cost and climate benefits of the two power technologies are compared for one California community.
"Bionic" Chip Will Aid Study of Neurological Diseases
The chip mimics the natural biological contact between brain cells, essentially tricking them into believing they are connecting with other brain cells.
A Solution for Phantom Load
All electronics have switches that turn electrical flow on and off throughout the circuitry. But unlike a mechanical switch, these waste small doses of electricity while they are in a waiting state.
Wireless Implant Helps Paralyzed Primates Walk
A wireless brain-control system recreates signals recorded from the brain and stimulates electrodes in the leg.
Autonomous Driving Extended to Scooters
Autonomous vehicle technology now encompasses scooters, potentially affording the elderly and disabled a greater measure of independence.
"BioSwimmer" Tested for Port Inspections
BioSwimmer has the ability to twist and turn in limited space within the water, which sets it apart from most other remotely operated vehicles.
"Sensing Skin" Detects Damage in Structures
The skin consists of three layers, which can be painted onto the surface of a structure or pre-assembled and attached like wallpaper.
Increasing Energy Density in Lithium Batteries
When lithium batteries are charged the first time, they lose 5%-20% of their energy in that first cycle.
