3D-sensing wristband opens possibilities for sign language translation, virtual reality
The researchers dubbed their device FingerTrak. It can sense and translate into 3D the many positions of the human hand, including 20 finger joint positions.
Crystal-stacking process can produce new materials for high-tech devices
To grow layers of single-crystal oxides for electronic components requires neighboring layers to interlock like Lego blocks. A new method throws out that limitation, producing new capabilities for data storage, sensing, energy technologies, biomedical devices and many other applications.
‘Magnetoelectric’ material shows promise as memory for electronics
Devices tend to store that information in two ways: through electric fields or magnetic fields. In the future, electronics could benefit from the best of each.
Optoelectronics origami: An easy-to-make, double-duty curved image sensor
The advance by a UW–Madison engineering team could lead to cameras with features such as infinite depth of field, wider view angle, low aberrations, and vastly increased pixel density.
New theory could open potent new applications for light
You’re in a large building, driving in a remote area, or even right in the middle of a big city, and you can’t stream video, check email or even make a phone call — because your cellular signal is weak. But the future may be different.
New technique could slash energy use in making silicon
A chemistry professor has come up with a more sustainable way to make silicon at much lower temperatures for the kind of advanced batteries used in electronics such as phones, cameras and laptop computers.
Team builds flexible new platform for high-performance electronics
An advance by UW–Madison engineers could enable manufacturers to add “smart,” wireless capabilities to any number of large or small products or objects — like wearable sensors and computers for people and animals — that curve, bend, stretch and move.
Thin photodetector could increase performance without adding bulk
The advance could reduce the size and weight of a series of solar panels, produce a higher-quality photo in low lighting conditions, or even transmit data more quickly.
A marriage made in sunlight: Invention merges solar with liquid battery
Solar charging and electrical discharging, according to a UW researcher, can be repeated for many cycles with little efficiency loss.
New computer chip manufacturing method squeezes more onto limited wafer space
Computer chip makers continuously strive to pack more transistors in less space, yet as the size of those transistors approaches the atomic scale, there are physical limits on how small they are able to make the patterns for the circuitry.
For first time, carbon nanotube transistors outperform silicon
For decades, scientists have tried to harness the unique properties of carbon nanotubes to create high-performance electronics that are faster or consume less power. Now, for the first time, University of Wisconsin–Madison materials engineers have created carbon nanotube transistors that outperform state-of-the-art silicon transistors.
