To increase the efficiency of microchips, 3D structures are now being investigated. However, spintronic components, which rely on electron spin rather than charge, are always flat. To investigate how to connect these to 3D electronics, physicists have created curved spin transport channels. They discovered that this new geometry makes it possible to independently tune charge and spin currents.
Read moreA group of researchers developed a highly sensitive rectifying element in the form of a nanowire backward diode, which can covert low-power microwaves into electricity. The new technology is expected that the newly-developed nanowire backward diode will be applied in using plentiful ambient radio wave energy in 5G communications, serving as a stable power source of sensors and contributing to battery-free sensors.
Read moreContact lenses that can monitor your health as well as correct your eyesight aren't science fiction, but an efficient manufacturing method has remained elusive. Until now. Researchers have reported developing a new manufacturing method to produce the lenses, solar cells and other three-dimensional curvy electronics.
Read moreScientists have succeeded in synthesizing sheet-like 2D polymers by a bottom-up process for the first time. A novel synthetic reaction route was developed for this purpose. The 2D polymers consist of only a few single atomic layers and, due to their very special properties, are a promising material for use in future electronic components.
Read moreA team of researchers has used stretchable materials to develop a battery that can be bent, stretched and twisted. For applications in bendable electronic devices, this is precisely the kind of battery they need.
Read moreThe Micro-Expressions Training Tool, inspired the hit TV show Lie to Me, is being used to train airport personnel to spot people who pose potential security risks.
Read moreA research team is developing EarEcho, a biometric tool that uses modified wireless earbuds to authenticate smartphone users via the unique geometry of their ear canal. A prototype of the system proved roughly 95% effective.
Read moreBiomedical engineers have developed a new platform to create biological drugs using specially engineered bacteria that burst and release useful proteins when they sense that their capsule is becoming too crowded.
Read moreSemiconductors — and our mastery of them — have enabled us to develop the technology that underpins our modern society. These devices are responsible for a wide range of electronics, including circuit boards, computer chips and sensors.
Read moreScientists provide solid calculation to demonstrate the structural transformation in colloidal crystallization can be entirely thermodynamic, in contrast to the kinetic argument, from both theoretical and computational perspectives.
