Normally, it takes pricey equipment and expertise to create an accurate 3D reconstruction of someone’s face that’s realistic and doesn’t look creepy. Now, Carnegie Mellon University researchers have pulled off the feat…
Scientists tap unused energy source to power smart sensor networks
A team of scientists has developed a new mechanism to harvest stray magnetic fields all around us and convert the energy into useful, usable electricity. The electricity that lights our homes and…
Charging cellphones with Wi-Fi signals using Graphene
Any device that sends out a Wi-Fi signal also emits terahertz waves —electromagnetic waves with a frequency somewhere between microwaves and infrared light. These high-frequency radiation waves, known as “T-rays,” are also…
A nanoscale device that can see through walls
Researchers at EPFL have developed a nanodevice that operates more than 10 times faster than today’s fastest transistors, and about 100 times faster than the transistors you have on your computers. This…
A device for the early detection of certain eyesight problems (e.g AMD
EPFL researchers have developed a device that can zoom in on previously invisible cells at the back of the eye. The technology could be extremely useful for ophthalmologists, in particular for detecting…
