A combined optical transmitter and receiver using perovskite
Researchers at Linköping University, Sweden, together with colleagues in China, have developed a tiny unit that is both an optical transmitter and a receiver. This is highly significant for the miniaturisation of…
Smartphone videos produce highly realistic 3D face reconstructions
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…
